Do We Need the 338 RPM?

Looks useful for a backcountry rifle. Lots of power in a lightweight rifle. More useful then the flood of little 6.5s and 7mms they keep coming out with.

[@bryanfox2735]

Sounds like you know nothing if you don’t understand what 7mag country is!

[@rockie307]

@@bryanfox2735 Nothing wrong with a 7 mag just stating the obvious which is we have over a dozen cartridges in the 6.5- 7mm range that are very similar with the newest ones only slightly better than the old ones. 6.5 creedmoor, prc , 26 nosler 28 nosler 6.5 270, 7mm weatherbys, 280 rem, 280 ai, 6.8 western etc. They all do very simular things. The 338 rpm does something different atleast. It's a short action with almost 4000 ft pounds of energy it's a a true big game cartridge shooting 200- 250 gr bullets. Pretty close to 338 win mag in a rifle this small and light is impressive. Alot of people hunt in grizzly country and feel more comfortable with a 30 or 338 caliber incase they get charged. Would you rather be going to recover your elk that maybe a grizzly claimed with 140 gr-175 gr 6 or 7mm or a 200+ gr 30 or 338?

[@aldeureaux5184]

You convinced me. I have a .300, and really don’t need it here in Texas. A .270 or, at most, a 7 mag is all you need. I have a friend from Africa whose family owns a farm with a hunting camp. We were talking guns one day, and I was surprised at their calibers of choice! Of course if they don’t get their game this week, they can always go back next week, not like if you are there on safari from the USA. His “normal” hunting rifle was a .308! I asked him “Well, what if you have to shoot a buffalo or hippopotamus?” (apparently hippos destroy crops and make a nuisance of themselves, as well are dangerous. He had talked about that) he said “We use our heavy rifle.” I asked what that was, thinking I would hear a .458, .416 or .375 at least. I was shocked that he said “.300 Win Mag.” without blinking or hesitation. He said it had proven to be all they had ever needed.

I talked with a buddy of mine about hunting in Africa. I mentioned thinking of taking a 338 WM for larger wildlife, and a 6.5 creed for smaller antelope. When I mentioned 338 WM he laughed - said it wasn't necessary. He figured a 300 WM would do just fine for most of the larger animals, and that the 6.5 creed would indeed be a good choice for the smaller antelope. Now, one could have a lengthy philosophical debate with the dude about one's choice of caliber, but the dude lives and hunts there, so he probably knows what works.

[@thebleeb1681]

Me too. My 340 Accumark is my elk rifle, and has a bit more oomph, but at the cost of weight of the 9 lug action. Carrying 2# less gun in the Rockies would be nice, but I'm so used my 340 handloads and ballistics that the extra expense doesn't cut it.

[@johanl1889]

You forgot one pro for the 338 over the 300. The 338 burns the powder a little bit more efficient, so they are a better choice if you want a little bit shorter barrel to put a suppressor on. The 338 rpm is available with 18" barrel, ready for suppressor. That is a big advantage for me and my kind of hunting.

Ron, I think this is another doomed cartridge. I had my ultimate North American rifle built and it is a 340wby that weighs 5.75 lbs with no scope. The stock fits me and with a brake the recoil is like a 270. I think when most people decide on 338 cal rifle they want the increased energy the big ones offer. I know thats why I chose it. Its very satisfying to shoot elk and they never take another step.

[@Blair338RUM]

The 338 RPM fits in a 06 case head and length action without going to a magnum action. So I have a switch barrel in 6.5RPM with a heavy barrel for long range work and a sporter barrel in 338 RPM. Both are incredibly accurate as well. One Defiance action and two Krieger barrels. Can’t get better.

[@therealgearhunter8935]

This cartridge peaks my interest. It only really makes sense in a Weatherby rifle though. Cause the weight doesn’t change between a true magnum and the RPM in any rifle other than the Mk V since in the Mk V they have two actions; the six lug and the nine lug. You can get the RPM cartridges in the six lug which is a pound lighter than the nine lug but you can’t put the traditional magnums in the six lug action. That’s the main reason for the RPM cartridges.

[@jeffreylocke8808]

I have to agree with you Ron and the heavier bullet mass makes a .338 caliber a great choice for heavy game. Even up to Cape Buffalo and Elephant with proper bullets and proper placement. Like WDM Bell and his 318 Westley Richards.

[@mothman-jz8ug]

As is the norm with the caliber du jour rifles, the 338 RPM is the perfect answer to a question nobody ever asked. But, as with each years crop of caliber du jour offerings, it provides an option for those who must buy whatever they are told is the current choices. After all, it is certain to kill game much deader (as much as 15% more dead!) than anything that came last year.

The .338 Norma is the chosen round for anti-vehicle sniping. During testing the Army determined the .50BMG was just too much, in too many ways.

Thanks for the excellent review Ron. I really like the Weatherby Backcountry Ti chambered in the 338 WBY RPM. I hunt in Alaska and as you alluded to, this would be a great mountain rifle in bear country. For myself, I’m a little concerned with the recoil in such a light rifle- I wouldn’t be hunting with the muzzle break attached (too much noise). I guess it is not that big of an issue since it’s a hunting rifle and I wouldn’t be shooting it that often. If Weatherby made the Backcountry Ti with a stainless barrel (instead of chrome moly) it would be even better!

[@HikeHuntHaul]

What a great video. That you for sharing Ron. I had considered the rpm but as a 300 win mag, 338 win mag, and 375 h and h guy; I’ll pass. That advantage might be in the rifle weight vs sectional density. Marketing these days by weatherby, Hornady, nosler, and all the other manufacturers is crazy impressive. I actually wish the 300 h and h would make its way back. But it seems the short actions are today’s sexy ticket. Thanks for sharing Ron!

I say do whatever suits your needs. I've always been more partial to the bigger, heavier, slower bullet crowd like 35's, 45's, and 50's. One of my top favorite calibers is the 45-70. Depending on the ammunition, it can be a light shooter or a heavy hitter. Then again, I typically hunt area's that aren't as open so I'm always taking a shot 200 yards or less. As far as a 300WM goes, I've seen that round down some impressively large animals, mostly on film, except the one time in person I saw my dad shoot a 1,256 lb bull bison 62 yards away. That round left one helluva hole and passed threw that bison, hitting a rib on the entry and taking one out on the exit. That was just a regular 180 grain federal blue box loading too.

Watch who tee who’s video on it. The accubrake is excellent for recoil it’s not bad at all. The rifle shaves over a pound off by being able to use the 6 lug instead of the 9 lug action is why.

[@jasonbroom7147]

The modern bullet manufacturing techniques, including various bonded and monolithic designs, has made the long held wisdom concerning sectional density less relevant. Smaller powder charge from the 338 RPM will create somewhat less recoil energy, so those very lightweight rifles from Weatherby might not rip your shoulder off, the way a very light 300 Win Mag will. It would also probably be a lot easier to load down a 338 RPM for less recoil. Personally, I would rather see it in 35 caliber, because of the options it brings to the table. It would be an alternative to the 35 Whelen.

[@jl123ist]

The belt on a case does control headspace, but that had little reason to use a belt, it was feeding in bolt guns for dangerous game. At the time belted cases came out double guns were popular for dangerous game guns. Two quick shots, they used rimmed cases for ease of extraction/ejection. When they tried these cartridges in bolt guns they often jammed up because of rim lock. They experimented with case design and found the belt prevented rim lock. I don't know if they tried a rimless case or not. They might have but liked the rimmed design well enough to extend it out and cut a groove for extraction was the way to go. Perhaps they thought rimless cases would be to much of a change for traditional minded hunters. Perhaps they decided on belts was it helped in bolt guns but was still easy to use in double guns. I never liked the belted cases because the extra diameter of the belt takes to much room in the magazine. Making the case rimless you could get an extra cartridge in the magazine. While hunting dangerous game that extra round might be the one you need to save your life.

[@HPAcustomriflesandcerakote]

I have always liked the 338win mag. So obviously I like the idea of the 338wby rpm.

A lot of people hear "9 lug" and assume that when its not as strong as a Win Model 70 or a Ruger 77 or other Commercial Mauser 98 actions.

[@cabochris100]

I'm in the market for a new rifle again and the 338 RPM is/was on my short list. Looking for a compromise do most gun. So am considering their 18 inch Backcountry 2.0. To use on everything from deer to moose, in Black Timber to mountains. Almost pulled the trigger, but have some reservations. First is the brake, which most likely must be used on a 5lb 338! So I would have to hunt with hearing protection, which is a new concept for me. I just called Weatherby today with some questions. I still am not sure if the barrel is stainless! At first the answer was no, then later changed to yes. So I really don't know. I did ask what I might expect the max range to be for elk and was told 400 yards. That's good, but was hoping a bit further, should such opportunity arise. My 300 Win is good for 400 Yards. But I believe the 338 RPM would hit harder, regardless of energy. 338 frontal difference is why. I think the 338 RPM is better than 300 Win. However, I most likely will pass on 338 RPM, regardless of how cool I find the package to be. I may sound crazy, but may go with Christensen Arms Ridgeline FFT in 300 RUM! Why? Because it's light, short and I have several hundred rounds of factory ammo. Despite having a 22 inch barrel, I suspect it would still be an honest 500 yard elk gun combo. Again, I prefer shots under 200, but just do not want to pass on an elk or black bear opportunity at 500. Obviously practice required. There are other rifles on my list, such as the Nosler Mountain Carbon, but for the price Christensen Arms FFT seems the best value? I've also thought about building something, out of a stainless 700 or Tikka. A 30 Nosler just might fit Tikka Mags. My 375 Ruger T3 does. The timing of this vid was perfect for me and helped to scratch the 338 RPM off my list. My 700 is a 300 RUM and might really shine with a 24 inch carbon fiber barrel as a do most, come what may rifle! I have a 28 Nosler Savage Ultralight, which might serve nicely for most NA hunting- only deep down feel 30 cal is better and a Frankenstein Rem 700 300 Weatherby. I'm looking to cut my arsenal down, keeping the 375 Ruger on the top end, finding my perfect middle ground do most rifle and then something for smaller game. Would like to end up with only 4 rifles for hunting/ practice and avoid ability duplication. The cool 338 RPM is off my radar now.

Your wasting your time and powder going with a short barrel on a RUM. You will gain nothing over any other .30 with a shorter bbl accept burning more powder.

[@John_Redcorn_]

Yeah i question why they didnt make it a 300 rpm

[@tmac5757]

I think the problem is going to be the price and that it is only shooting the same as the good old reliable 338 Win Mag so why waste the dollars buying something that only Weatherby is the most likely producer of, I have not seen value for money when it comes to Weatherby cartridges or cases. My two cents worth. Still great info though Ron. Cheers from the Land Down under. Terry

[@thomasdaniel6495]

I'm hoping Weatherby will come out with a 30 cal version.I am a big fan of the Winchester version,but I do hate the belt.I think the backcountry 2.0 would be even better in the 30 cal.,but that's just my humble opinion.

[@jcarry5214]

I bet they’ll get there, but competition with wsm doesn’t sound like much fun, not much new ground to cover would be my guess. A new 338 built around current bullets is pretty interesting, I bet it gets a following like the 6.5 which had a lot more competition.

[@tompeavy5357]

If you are referring Winchester 100 auto or 88 lever they have closing bolt system as so does the finwolf

[@jk-kr8jt]

I like all my Weatherby's, rifles and shotguns, but I believe Weatherby missed on this one. Sure a light rifle is a great thing to carry. But a new expensive rifle in a cartridge that will be expensive and hard to find, just won't appeal to most hunters. Plus, let's not forget that when the 338 Win came on the seen it was shinning with 250 grain and 300 grain bullets. Big bullets for big heavy game at close and relatively close range. That is why Winchester released it in the model 70 "Alaskan", think moose, brown/grizzly and polar bears. I'll stick with my 338Win, 338RUM and 340Wby. If I need bigger one of the 375s or the 416Wby comes out. Maybe some day the 35s will be rediscovered.

[@sandflea2424]

Exactly, get them to modernize the 35 and take a much bigger step forward.

[@toddk1377]

35's are a good size to weight ratio. I've bagged a few deer with a 35 Remington and I was surprised how well it performed. From the numbers on the box, it didn't seem to be much of an upgrade over a 30-30, but it was definitely an upgrade from the looks of the wound channels.

[@rockie307]

I'll take me a 338 rpm 20" barrel and a lightweight 1-6 scope for backpacking hunting over a long barrel 300 in grizzly country any day. Can't think of a better setup for that purpose. Bigger bullets typically kill better on big game which ballistic charts dont show. Most people are obsessed with bc and velocity these days which never hurts but for hunting a elk or moose at 400 yards or under bullet size and mass matter way more then bc and a couple inches trajectory difference. The bullet is the only thing that actually touches the target.

[@gregorychang8406]

The most interesting .338 for a long time is the 8.6 Blackout. It should definitely be in this lineup. It’s nice to see something truly different…

[@rosshill2565]

The only issue is 8.6 is not hitting anything at 300 plus yards. 8.6 is just fine for 100-150, maybe 200, with a drop chart.

[@REDNECKROOTS]

That 338 def has the thump for close range out to 200yards. Bet it would be awesome whitetail round in the north woods ware I live. Shoot a real heavy 250gr That really seems like it's at its best inside of 200 energy wise. Them whitetail be shaking in there hooves

[@robertsebacher44]

If you can put the time, money, and effort into making a 500 plus yard shot ethically in a big game hunting situation you are among an elite few in the hunting world. Point Blank Range should be the limiting factor for the common man with cartridges and bullets that are effective at less than 500 yards. Just the opinion of a common man who used to love hunting. I don’t claim to be an expert. I try to be ethical. My personal limit I restrict myself to what I can take with a 7mm REM Mag with a 175 grain bullet. For whitetail I normally use a 308 shooting 173 grain Hornady bullets and I have a rifle that lets me stretch PBR out to 325 yards but I have never shot anything except ground hogs and coyotes at close to that distance with the 308. I think we are going the way of Europe and soon only landowners and the very rich will be able to hunt. As a common man maybe I need to trade my hunting gear for what is more suitable to defense and range shooting sports. Actually at my age I should just let the young ones worry about it and be thankful I lived when I did.

[@linklesstennessee2078]

Yep need anything we can get ahold of

[@howdypardner4128]

The Weatherby RPM cartridges are niche rounds catering to 6_lug Mark V customers demanding the lightest weight rifles possible. There is no other reason for these cartridges to exist.

[@csjrogerson2377]

Not needed in North America. Plenty of choice already exists. It's just marketeers trying to get their share of the market.

[@lynndragoman2454]

The 338 Norma or 338 Norma Ackley Improved is probably the best all around 338 made today. The 338 Lapua has the wrong throat for 300 grain bullets and with solids none will fit in a magazine and get best accuracy.

[@Weatherby406]

Weatherby has a fantastic muzzle brake. Iv seen women and children shoot a 30-378 Weatherby with no issue. It’s shocking how light it is.

[@jcarry5214]

Interesting. Is it belligerent on the ears, can it be used hunting without too much pain?

[@andyeighttre]

What!!! Huh??? I didn’t say season the brisket with 7 up.

[@bluemountainsports1657]

You have to bring up .325 and how great it is in a light rifle 8.25lbs with a scope. As well as how it died because nobody really understood that the only reason to get one is to have a light rifle. You can compare it to several other cartridges and you see it shoots about the same. In Eastern WA you can expect to hike far 5-10 miles and shoot far 500 yards. These western hunts go great with western rifles. But how many people are doing that?

[@rangetime6779]

Good information, it'll never be very popular and expensive to shoot.

[@borisptitsyn2130]

Like every Weatherby cartridge 🤣

[@nebraskaman8247]

What attracts me to this is I’m kinda wanting a 338, and I got a Borden action about to be delivered with a non magnum bolt face. So do I go with 30-06, 30-06ai,338-06,338-06ai, 338rpm, or 30 Gibbs…oh the possibilities

[@josephlong7420]

I guess not being much of a hunter, I just don't get 95%of new cartridges. I figure if I cant kill it cleanly with a 308, 30-06, or 7mm rem mag I probably don't need or want to hunt it.

[@davecamilleri9411]

To make things fair, a .650 BC bullet in a 300 win is a high bc bullet, so why not compare a 338 250 gr high bc bullet with a .685 bc or step it up a little, a 300 gr Nosler Accubond has a .720 BC and a 300 gr Berger has a .818 BC. The 300 win mag is a great round, so are the 338's and sometimes the bigger hole does great things. For reference I shoot a 338 RUM and I push 225 accubonds over 3200 and 250 gr at 3050 and 300 gr at 2850. I am also loading 225 bullets in a 338 win mag at 2925. I also shoot a 300 RUM and I push 180 grs at 3350 and 215's at 3030 with a .696 BC. If we go back to hunting bullets of old like the Nosler Partion in 30 Cal, the BC will be below .500. As I get older the idea of a .338 in a lightweight rifle is appealing. I might just have to take a ride over the Big Horn Mountains and go visit Weatherby!

And 9.3*62, but it's a 36cal

[@dantyack1059]

maybe i’m not all in the “know” but…. i don’t know anyone at all that shoots a 220 gr. bullet in a .300 winchester for hunting… i don’t even know anyone that shoots a 200 grain bullet in one for hunting.. …. all the hunters that i know either use a 150 or 180 gr. bullet with a few others using 165’s .. i may be wrong but i think this comparison should have had the .300 shooting the 180 accubond because that is the best normal option..… I would be willing to bet that is the load 90% or more of the elk and bear hunter’s use in the .300 winchester.. this comparison uses the best possible scenario for the .300 win and just what you get for the .338’s.. in my opinion this isn’t a fair comparison in any way…

[@albertjabberin739]

I don’t know if I buy the 300 win mag numbers being better, at least with 220gr. Either way, a cartridge shooting a 220gr round at 2800+fps out of a 5-6lb rifle sounds painful, when that same mark v 6 lug 30-06 can have some good kick.

[@jazon9]

.338 Federal is so nice. Especialy you can shot this in your AR-10 style rifle!

[@wcndguy5302]

A non magnum with more energy than a 300 mag at short range. Ideal for grizzly and moose in the bush.

[@hotramen5952]

can we get a .338 "western"? .338-06 performance in a short action with 225 grain bullets with the modern super tight chamber specs like the creedemores, westerns, and PRCs. super efficient case design would lower recoil probably to .30-06 levels but with big ole bullets for the 300 and under crowd.

[@borisptitsyn2130]

Currently they are a foolish company. They could move some levers to change for the better of their shooters but they don't.

[@mattandrews8528]

This is why .308 is king. Ammo cost and availability trumps overkill ft lbs of energy. I love my .338 Win Mag Bar, but I absolutely f*cking hate trying to find and afford shooting it to the point my AR308 is king. It’s a much softer shooting platform even when compared to a gas operated .338WM BAR. ALL of the new expensive ammo doesn’t matter in my opinion if I’m shooting 400yds or less. If I need to shoot farther then a .300 Win Mag is the best choice, once again ALL because of ammo cost and availability, plus it’s very easy to find a used or new rifle in .300 Win Mag. All I need is .300blk for close range up to 150yds or so, a .308 for intermediate and “long” hunting range up to 4-500yds, then ya got .300 Win Mag for hitting hard up to 800-1000yds. Anything past that you just need to get closer to your target before pulling the trigger. New cartridges are like new pricy fishing lures, they’re mainly to catch the fisherman’s wallet and not so much the fish.

So, it's basically a hotter 338 RCM. Guess we'll see how much this niche market will keep it alive. Most likely Weatherby will be the only one to load for it and keep it afloat like their other unique cartridges.

Should I clean it ? If I don’t is it bad for the barrel? I normally clean it after every shoot and get all the copper fouling out.

[@forkthepork]

Go watch tiborasorus rex sniper 101...

[@Mountain-Man27]

Yeah what he said, but short answer is you do NOT need to clean the bore after every shoot. You should only clean the bore when you notice a degrade in accuracy. Keep all the other parts as clean as you want but you’re actually not doing yourself a favor and probably hurting yourself more than helping by cleaning the bore that often. Watch tibosaurus’ video though like the guy above said.

[@toddk1377]

What these guys said. Rex explains the importance of copper fouling and such. If you do clean it 100%, you'll want to fire a few rounds to get that accuracy back to where it was. This is also the same reason why new firearms sometimes seem inaccurate at first and then after a few rounds the groups start to tighten up.

@@Mountain-Man27 thanks for the reply I was at the gun range checking my Zero and got 5 bullets all touching! With Winchester ballistic silver tips 200 grain at 100 yards so I don’t want to ruin that, so should I just run a patch through with some gun oil for storage?

[@Mountain-Man27]

@@jayfry905 you won’t lose the accuracy permanently if you do clean it properly. The only thing is that after a cleaning you will need to shoot a few shots before the groups will tighten back up again. I may be doing it wrong but I store my guns in a safe with a plug in dehumidifier so I don’t see the need to run anything through the bore at all after shooting. I’d only do the oil after you’ve cleaned it.

[@gregeoryl]

Truthfully, how many times in my lifetime has there been a real standout cartridge? Maybe 500 S&W, 6.8 SPC? Most others are super marginal improvements in hopes of narrow advantage in competition shooting, or tailoring to a specific gun.

[@ExF1Guy]

The RPM seems kinda disappointing to me, at least based on Weatherby's numbers. In an 18" barrel with a 225gr bullet, they are claiming 2615-2660fps. In my Tikka, with a 19" barrel, I am able to achieve up to 2847fps with a 225gr Nosler partition. No pressure signs. This is a max load, not necessarily the accuracy node. For the distances I shoot, a .5 MOA group is a minimal advantage over a 1 MOA group. Perhaps handloading could remedy this discrepancy with the Weatherby cartridge. I know the 185gr GMX factory offering dropped about 200fps in my rifle. Weatherby typically pushes speed though... With minimal modification, the Tikka comes in at 5.65lbs. Replacing the stock and lightening a few more components should get me right around 5lbs. I'm sure the Weatherby is a quality rifle, but I'd rather put in a little work on the Tikka and save myself $1500.
