300's Compared

Randy starts off with a series of talks comparing similar cartridges, with a comparison of 4 of the .300 calibers: .300 Win., .300 PRC, .300 Wby., and .300 RUM.
How do they compare, given all using the same or similar loads?

Long live the 300 RUM. I remember when Remington released it with power levels 1,2 and 3. It was 30-06 level, 300 win mag and full house and I thought it was a good idea but nobody does it that way now.

[@johnnorman7708]

@Scotty Davis. That select a level idea was great, but the buying public is sort of fickle on stuff like that. Back in the old days .270 Winchester ammunition was offered in two levels so woods hunters could have a milder less destructive 150 grain deer load. It was about like a .300 Savage for speed and power. Perfect in concept. That load sold poorly and was dropped. Such is the market with buyers. All or nothing.

[@jk-kr8jt]

I hated the I, II, III power levels. If you want 30-06 power shoot a 30-06. The ammo availability in my area was always the 06 level, or occasionally the 300 win level. It was a joke on Remington's part. I like my 300 RUM but Remington did a poor marketing job with it. I recall their original ad campaign comparing the Win, Weatherby and RUM. In typical BS fashion the compared them with the RUM having a 26" barrel and the other two in a 22" and 24" barrel. Like I said I like/enjoy my RUM , but it is not any faster or better than my Weatherby's.

[@azbushrat]

I like the original 300 magnum, the 300 H&H.

[@pauldeahl3980]

I do too. The H&H is the Goldilocks of the the 300’s. If you look at the 300 Win Mag for example, it’s so inefficient. If you don’t want to use the H&H, at least consider the 300 WSM before just getting a 300 WM.

[@mikeyoung6127]

.300 H&H delivers essentially (95%) the same performance as the .300 WinMag. The longer neck increases the stiffness of the loaded cartridge, so if a round hits the ground, the bullet will still be straight. I have a number of friends with .300 WinMags, but the recoil is almost double that of the H&H. As I prefer to watch my misses as they happen, the .300 WinMag doesn't work for me. The long and tapered cartridge body, combined with the slowly tapering neck dramatically reduces recoil and makes operating the bolt much smoother. I have never had a case that was reluctant to come out. Picking up spent brass at an outdoor range, 1/3rd of the 300 WinMag cases I picked up the case head was torn behind the extractor groove. At the cost of belted magnum brass, I will be happy with my 1888 Gewehr and my Remington US Model of 1917, both rebarreled to .300 H&H.

[@aaronwilcox6417]

I've had most of these over the years 30-378, 300RUM, 300 Weatherby, 300win mag, 300WSM. These days it's very costly to get good bullets and impossible to find 338cal and 375cal at present. For this reason I've found 270win 308win and 30-06 to be available and at least components easier to find so that's what I'm using. I realize my 270win isn't an 300 Weatherby but at least I can buy ammo and cases to reload for it pretty easy.

[@MichaelRandall-f1o]

I've built 2 and reloaded 3 300 magnums. 300 wsm, 300 Rum, and reloaded the 300 win mag. The 300 wsm uses 8 - 10 % less powder. And keeps up the 300 win mag up to 180 gr bullets. I built the 300 Rum for longer ranger shooting. Reloader 19, RL 22, IMR 4350, IMR 4831. work good for me. I've used Winchester and Federal pimers. With 150 - 180 grain bullets for deer or elk. Ive reloaded 18 different calibers over 24 years. The 300 wsm is my favorite 300 magnum. less powder and recoil and the best accuracy over a boarder bullet weight point of impact.

[@WantingWilderness]

While the case capacities are similair between the 300winmag and the 300PRC, the PRC has 1000PSI more working pressure under SAAMI and because the bullets are seated further out of the case, heavy bullets don't eat up eating case capacity. We're able to see about 10% improvements in velocities between the 300wm and 300PRC and that's significant.

That was very well presented! Very good information to have ! The different powders were covered very well !

[@vettepilot427]

Randy, thanks for your opinion. I'm a gunsmith also, and I think the advantages of the 300 PRC are that it does not have a belt like the standard magnums which can help accuracy and it allows heavy for caliber bullets and longer cartridge OAL so there is an advantage over the 300 win mag in that regard. Is it a huge difference? Not really, but why not take all the advantage that you can get with everything else being equal. Also, a lot of my customers don't reload, and the other advantage to the 300 PRC is the cost of ammo vs the larger capacity magnums. Thanks again for these videos.

[@TODinWY]

In this day and age, hopefully short-lived, ease of finding brass has to be taken into account. That puts the 300 Win Mag at the top of the list.

[@vettepilot427]

@@TODinWYAs I said, a lot (actually most) of my customers don’t reload, so they’re looking for the best out of the box performance that they can get. Performance for them is accuracy, power, manageable recoil in a light rifle, and ammo cost and availability. 300 PRC ammo runs about $65 per box for hunting ammo and that’s a 212 gr ELD-X bullet at 2900 fps. I’m not sure availability of the brass (I’m sure it not as common as 300 win mag), but the loaded ammo is readily available. With factory ammo, there’s about a 20% increase in performance and still have decent barrel life (compared to other magnums) and low cost of ammo (compared to the hot mags like the RUM and Nosler).

[@redrock425]

Not reloading leaves so much on the table. I was all for 300 PRC but now a properly throated 300 Win mag seems like a great option.

[@vettepilot427]

@@redrock425 There’s not as much left on the table as there used to be. I’ve measured SD’s for factory ammo that were in the single digits, especially Berger factory ammo. Our rifles routinely go under 1/2” with factory ammo and we’ve had some that hit sub 1/4”. Once you get to that level, there are so many other variables to accuracy in hunting situations that it’s almost pointless to try for better. The advantage of reloading these days is there are so many cartridges, that it’s hard to find factory loadings for all your favorite bullets. It will be a cold day before Nosler loads factory ammo for a 300 PRC. So if you want Accubonds or Partitions for your 300 PRC, you’re gonna have to load your own. As for 300 PRC vs 300 win mag, if you’re loading your own, 300 PRC is even more favorable. You have a larger case volume, and a wider selection of bullets since you have a longer COAL. You can pick up where 300 Win Mag stops.

It also separates itself from the 06 when shooting 200+ grain bullets Especially when hsndloaded

[@someguysomewheresouthern6290]

I’d read and cruised through forums for about 6 months trying to decide what to get as a magnum rifle. I live in the Southern US where I can take every larger game animal with .30-06 or .308win, and have for 30 years or so. Decided I wanted to go out west in the future, so I went initially with a .300win mag in a Savage rifle. Shortly thereafter, a friend decided to sell his new Savage chassis style rifle in .338 lapua mag, so I picked it up as well. I’ve shot the .300 quite a bit and love it, the .338 is ridiculously expensive but shoots well also. Thanks for the experience with the bullet types and manufacturers, I’ll definitely be taking advantage of the info! Thanks sir!

[@douglasborgaro6801]

The 300 Weatherby is a timeless classic! Some shy away from it due to cost. The RUM does not really beat it. The difference of 50 to 75 fps is not a real advantage in the field. Stuffing more powder into a slightly larger case also pushes barrel life to a point where practicality is a question. I have found considerable differences in performance between the Weatherby and Winchester. My chronograph testing has shown over 100 fps advantage with numerous weights when compared to Winchester 300. I’ve recorded 3095 fps with 200 grain round in the Weatherby. Accuracy was superb. All in all the 300 mag, for whatever version you pick are fantastic performers.

[@tca375]

Thank you for sharing your test results.

[@stephenland9361]

About 35 years ago I purchased a bolt action in .300 Win Mag. It's made by Krico, a now defunct company from (the then) West Germany. It's been a tack driver straight out of the box. On one excellent day, I got a one half inch group at 200 yards. That's quarter minute of accuracy. Not bad for an off the shelf rifle. With a hand load I worked up, I'm getting 3,000 fps with a 180 gr. bullet out of a 24 in. barrel. That's plenty enough velocity (and energy) for me. Recoil is stout but manageable. I understand that greater velocity means more energy but if you've got enough, why chase more? I don't do long range shots at game. My solution to a 700 yard shot is to get 500 yards closer. I do some long range shooting at my local range where it goes out to 1,000 yards but to me, hunting and target shooting are two different things. Having an excellent 30 calibre magnum rifle in my .300 Win Mag, I don't see the need for a Weatherby, a .300 PRC or whatever. If I was just starting out, I'd look around... and likely choose the .300 Win Mag. It's enough gun for elk, moose and bears. It's an excellent cartridge for the mountains. If you have to 'reach out', it can do it. (But try to get closer!)

🤠 Very good discussion and I can wait to hear more! That being said, I used to have some Bigger 30's, one of which was the Lazzeroni Warbird! It's case water capacity was 130 grains, while the 30-378 Weatherby is 133 grains of water! However, the pressure rating for the Lazzeroni Warbird was 66,000 psi, while the 30-378 Weatherby was roughly 63,000 psi! That difference in pressure, 3,000 psi, enabled the Lazzeroni to push a 180 grain bullet roughly 150 ft/s faster! However, I had to back off on the velocities 150 ft/s just to get it to shoot! It was rated to push out a 180 grain bullet at 3,600 ft/s and a 200 grain bullet at 3,350 ft/s, but backed it down to 3,200 ft/s for my 200 grain Swift A-Frames! So, it somewhat defeated the purpose of getting it in the first place! If I were to buy another 30 caliber (though my 30-06 has served me well), I would choose old Roy's 300 Weatherby Magnum! I have shot and seen game shot with my uncles and friends, 300 Winchester Magnum, 300 Weatherby Magnum,, 338 Winchester Magnum, my 338 Lapua Magnum, and Uncles 340 Weatherby Magnum! To me, the 300 Weatherby Magnum is enough gun, without overkill! I had 3 butchers in the family and they all hated Magnums, due to excessive meat wastet! After 45 years of hunting, I now understand their position! However, you touched on another Very Important Point - Bullet Construction and Selection!

It didn't matter how many different powders, primers, etc I tested with each of these cartridges. With a 210 LRAB, and a 26" barrel, ALL 3 cartridges pressured out at 4300 ftlbs of energy/3040fps at the muzzle. There was ZERO advantage for the 300WBY and 300 Ultra, over the 300 Win in 26" barrels. I am convinced the barrel needs to be longer to see ANY appreciable difference between those 3 cases. My buddy is a gunsmith and he found the exact same thing to be true in his own testing but with 180gr bullets. Another buddy just built a 300PRC, we will be testing that shortly.

And you may have a "fast" barrel Dave. In my internet travels, I have found my 4300 ftlbs in a 26" statement to be really accurate for those 3 cartridges. Once in a while, you can wring a bit more out. As Randy said, across the hundreds of rifles he has chambered in these cartridges, it's always 4200 ftlbs or so(based on velocities and weights he stated in this video) and I know he usually holds his barrels to the standard 26 inches for magnums for his clients.

[@timmcfarland3311]

300 Rum. I built one for king of one mile 33” barrel and it pushes the 245 Berger bullets at 3140 FPS my Chamber is 4.150” and I seat at 4.125” and it’s a hammer only factory case that beats it is the 30-378

[@ronaldroehrick4872]

Randy is the absolute best there is IMHO.

[@johnnydawson7675]

Three cheers for WC860! I have used it in the .378 Weatherby.

[@trevorj.8401]

Thank you again randy for taking time out of your days to to share your expert thoughts and knowledge. I Would love to hear Randy's thought about the 300 norma mag maybe one day on the future

[@k4391]

Look into the 300 Norma improved very nice case for heavy bullets

[@tylarhaugan7908]

Randy my first hunting rifle was and is Tikka t3x lite in 300 winmag. Since I have 1 in 11 twist I use 168 ttsx. And 190 accubonds. My barrel is now 20 inches and i put asr 3 port break. Im 6'5 so that extra 4 inches wasn't fun

[@warreng2885]

Been using the 300WM for 30 yrs on elk, nilgai etc. Great results with nosler partitions. Have switched over to bonded bullets..accubonds and terminal acsents with much better accuracy.

[@finallyfriday.]

Savage 300 and 300 H&H. Throw in a 12ga and a .22 and you have all the guns you need.

[@craigleibbrand7761]

Throughout both 300 replaced with 30 ought 6

[@travissmith-wz5nc]

Hard to beat a 24 to 26 inch barrel on a 270, 280 or 3006 hand loads. If twist was spread up to 1 in 8.5 new cartridges are not needed.

[@WantingWilderness]

if your hand loading just rebarrel, the problem is factory offerings. When some guy grabs a heavy box of 270win and doesn't have a proper twist, he'll complain its garbage ammo.

[@travissmith-wz5nc]

@@WantingWilderness I started reloading the hammer bullets. Most accurate copper i have found

[@WantingWilderness]

@@travissmith-wz5nc I have a few boxes but haven't tried them yet. Have you taken game with them yet?

[@travissmith-wz5nc]

@@WantingWilderness Yes. Entry is diameter exit is tennis ball size at 175 yrds. I bought the 270 rounds (.277) 117 gr and 124 gr. I would stay with 117. Start at 57.5 gr 4831sc. 3.25 and start opening up by .05 till pressure heats up.

[@quarterminutemagnums]

We build a lot of 30 Noslers with 210g Bergers. Q.M.M.

[@rodneyhickman825]

If I was interested in a 300 then I would pick the 300 wsm .

[@406life]

Good stuff Mr. Randy, an extreme long range shooter out of Australia actually found that the old win mag outperforms the prc in the high bullet weights

[@Mountain-Man27]

That sounds likes bs to me. 1 grain of powder difference is nothing sure but it’s designed for longer and more efficient bullets. The 300 wm can’t even fit some of the higher weight bullets without increasing the length of the action.

[@YERAFirearms]

The PRC would excel at the 225-245gr VLD, high BC bullets

[@freedomforourfallen3755]

Win mag. Love it. Rum is sweet but if I need more. I’ll just move up. Lapua AI I use the 180 AB. At 150 key hole. Still working on the 190.

[@garybaldwin7432]

Hi Randy what lead free bullets do you recommen for the 300 weatherby Magnum. We're I live they only allow lead free bullets for hunting Thanks .

[@TheRealGunsmith]

Barnes X, Hornady GMX and CX, Nosler E tips. Good hunting. Thanks for watching.

[@johnnydawson7675]

Randy, what do you think of Ramshot Magnum powder in the three hundred mags?

[@TheRealGunsmith]

I've used it in the .300's and it has worked at times, but not my first choice by a long shot [pun intended]. Thanks for watching.

[@rebelwolves]

Sure the .300 win mag and PRC are close at those low weights.. but that is taking the PRC away from what it was designed for. It was designed to fire heavy for caliber bullets. Hornady has a great story on how and why it came to be from custom built .300win mags that were made to accept rounds much longer than SAMMI specs and use short twist rates. Many people only ever look at the 500yrd data and say there is no reason for the PRC to exist... however, if you look at the 1,500yrd data, it is a completely different story. For me personally, I do 90% of my hunting with .308win. I use .300PRC for sport shooting (1,000yrd). If I need something for some longer range hunting (elk/moose/mule), then I have my .338 Lapua which will get the job done on anything in North America.

[@AbesNbacon]

I beg everyone to turn off the comments and just listen to Mr. Selby. The information he’s giving away for free, is priceless. After the video go back and leave a comment. You can absorb his information and read the comments at the same time.

[@ja0298]

300 prc wins it for me. Modern case and chamber design made long range shooting from the get go.

[@samstewart4807]

Hi and wow. Is your .0005 case expansion rule generally followed by other hand loaders? Or do many? other handloaders like a different amount of expansion?

[@TheRealGunsmith]

This is .0005 maximum acceptable expansion, as going any further expanding the head will result in more expansion and loose primer pockets eventually. Thanks for watching.

Have they already stopped running guided elk hunts in Wyoming due to wolf predidation? I have heard the wolf predidation is really bad in Montana.

[@ronlowney4700]

🤠 Yes it is! 😭 If you come this way to hunt, by yourself a wolf tag! 🐺 One wolf, on average, eats 90 elk per year! 😡

No, though it is very slim. Our son quit guiding as the pickings are so slim.

[@vikingstorm32]

Everytime I watch your videos, I never know your name so I write santa next to each idea you give me.

[@gw5436]

The 180 Accubond is an awesome Elk/large deer projectile. Works wery well in my 300WM, and equally in my 300RUM, which really tests a bullets ability to hold together.

[@jasongavel2787]

I haven’t had a problem with my 300wsm

[@ronkay1573]

What about the 30-378 Weatherby mag?

[@TheRealGunsmith]

One needs to burn 20-25 gr more powder to equal the .300 Wby. velocity. So, if you like the 30-378 Win. Mag and don't mind the extra cost, overall, of those extra grains in each load to equal the .300 Wby, then go for it. I prefer the .300 Wby, for performance and lower charge for the velocity over same charge in 30-378. Thanks for watching.

[@dbeardsley0]

I just enjoy the 30 caliber. Got a long range shooter in 300prc and 308, a hunting rifle in 300 win mag and 300prc

[@robjohnson6747]

AMEN ! PRAISE THE LORD AND AS ALWAYS WITH YOU RANDY ! BINGO BINGO BINGO !

I have the 300 prc and want another 300. Can’t decide between the 300 wm or 300 wby. Any help lol

[@bartowpd342]

I’m so thank you answer you comments, by the way 300 prc was made as a turn key reference 300 wm having to be specially made.

[@paulhazel5754]

again, thank you!

[@jaybailleaux630]

Any 30 cal cartridge that can throw a 200 grain bullet at 3000 fps or better is just plain awesome. Elk, Moose, and all African plains game and the largest mountain rams will be flatten with a hit in the vitals. Elgin Gates proved that with a 300 Weatherby long time .

[@ronkay1573]

What characteristics make a cartridge efficient? I’ve always read the read 308win is efficient. What makes it more efficient than a 300 win mag?

[@TheRealGunsmith]

Case capacity. Thanks for watching.

[@triptideom]

Thank you

[@buckeye8069]

Thoughts on 180grain in 300 wsm and 300win for elk?

[@woodycartis7977]

The 300 Norma Magnum seems to have the best BC in the heavy bullet. The military has just selected it for a sniper round.

[@dennissheehan7930]

The 300 Norma cartridge doesnt have “Bc”. The .308 cal projectiles its fires they have a “ Bc” ……

[@jkeverline1]

Randy, Are you loading the .300 Win Mag to a COL of 3.600? Also, At the NRA Convention I spoke to a gentleman with Alliant Powder and he said they were discontinuing Reloader 22 and several other powders. He suggested I switch to Reloader 23. The problem is there isn’t any data for Reloader 23 in some of the cartridges I shoot. He also said the new powders would have a TS (temperature stable) designation such as the recently introduced Reloader TS 15.5.

[@TheRealGunsmith]

.300 Win COL will depend on the bullet design and make. 3.460 to 3.560. Thanks for watching.

[@jkeverline1]

@@TheRealGunsmith Thank you. I had a Ruger M77 and had to keep the COL under 3.340. That really reduced the powder capacity with 180 and 200 grain bullets. I sold it a long time ago and switched to the .300 Weatherby.

[@davewagner5408]

Just curious,don't you use any IMR powders. I've had good luck with IMR 4350 in several different cartridges. But I'm not as meticulous as you.

[@TheRealGunsmith]

Yes, I do. Thanks for watching.

[@davewagner5408]

Certainly,sir. You're the kind of man I encourage my step son ,who is interested in reloading to watch. You know what you're talking about. To many you tube heroes pretend they're educated,and if beginners listen to those guys, they'll get hurt. I'm fairly knowledgeable myself,but you're a step up,keep it up.

[@tbjtbj4786]

I believe I will stick with my idea since I was 20. If I need a 300 I will just use my 338wm.
