According to an Ammunition Data Card from 2009, this is the load for M118LR: Federal Cases (military uses modified Federal GMM cases) Federal GM210M primers 41.745 grains IMR 4064 SMK 175 grain HPBT COAL 2.83 Your 41.5 grain load looks to be a good M118LR copy. Nicely done.

[@DummyRound]

Awesome. Thanks for the info. I need to load some and verify the charge.

[@chaddfry5345]

Great start to that load! You can confirm the results of the 41.5 gr load and/or do some seating depth tests on the 43.0 or 42.5 loads. Great stuff!

[@DummyRound]

I'll probably load a few back at 41.5 just to confirm it or see if I got lucky first. After that I definitely want to play with seating depth at a higher charge. Thanks!

[@katashi222]

Well done, nice to see another .308 shooter. Same power, but at 45c 175gr speers and / or burger, same primer. 600m stacing em bullseye out to 800m one hit.....the wind was wicked that day....switching every 10 secs. Howa M1500 APC chassis .308.....i think is dialed in....ready for some FClass competitions.

[@DummyRound]

That sounds awesome. The furthest I can shoot around me is only 300 yards. Thanks! 🇺🇲👍

[@andyprairiedog4829]

Very interesting on your load development. That 41.5 grains looked very promising. Also, to the patreon member, Thank you for the donation for this video.

[@DummyRound]

Going to load some to confirm at that weight and then play around at 42.5gr with some seating tests as well. How fast was your SW Match Rifle load going? I have some of that to play with as well. Thanks, brother!

[@andyprairiedog4829]

@@DummyRound Using Hornady brass, Federal #210, my SW Match powder went well with an OAL of 2.800" (magazine length), 43.5 grains at about 2,609fps out of a 26" barrel with 1:11.25 RH twist.

[@DummyRound]

Thanks, good to know. It is a lot cheaper than 4064 and I have a lot more of it as well! I'll probably give it a try here soon after I'm finished with 4064.

[@guardianminifarm8005]

Thought I would check you out after you sent 30/06 John some components. Appreciate your kindness. I have a decent older Rem. 700 vssf in 308. Like the 308 for all around option.

[@DummyRound]

Hey, there! I appreciate you stopping by. 308 Win is a hard to beat cartridge for anything in my neck of the woods. I'm still learning to be a better shooter, but this old Browning A-Bolt makes it easy. Thanks!

[@jj-eg5up]

Great video. Thanks for not making us watch you shoot all those rounds.

[@DummyRound]

Thanks, I need to load some more of these.

[@BOHEMIANHUNTINGCLUB]

Lawyer friendly data👍🍻😀

[@DummyRound]

Starting low is great and all, but we don't need to start 25% below max 😂

[@rickm4295]

43.1gr is my load with 175 SMK. Anywhere from 42.6 to 43.6 is good but 43.1 and 43.2 are best for my SPS 20" 1-10 twist. My case base to shoulder is 1.4845 with a .002 bump. 5 rounds in a .383 hole just about every time as long as i dont sneeze or anything....

[@DummyRound]

Sounds awesome. I need to verify these loads, but it's a good starting point. Thanks for sharing🇺🇸👊👍

[@politicallyinsensitive4200]

I'm not sure why everyone fawns over Federal's GMM. I took some 175's from Federal (Gold Medal Match), Norma (Golden Target Match) and PPU (match) and from my rifle the PPU grouped the best at just under 0.75". @ 2607fps.

[@DummyRound]

Idk, either. I've never shot the factory ammo, or any of the ones you listed. Seems like it was what people wanted to shoot before all the 6mm and 6.5mm came out in the last few years/decade. My gun likes the projectiles so that's what I use most often. Thanks👍👊🇺🇸

[@kentuckywindage222]

​@@DummyRound I've been loading 175gr Matchking for a little over 5 years. I found the consistency of their bullet very good compared at the time price for price. I have used IMR4064 in Federal, Winchester and Lapua brass. Winchester is for the money better in my opinion than Federal. Lapua being the best out of the the 3 per times loaded. I have one lot with 12 loadings. Pockets are still good and last outing to 1000 yards yielded great accuracy. No line inside or out and I checked each case just to see with a bent paper clip dragging up inner wall. In warm weather Hodgdon CFE223 give me best velocity but is more temp sensitive. I found it shot below .36 and almost exact same point of aim from 45.0 to 46.0 gr. 46 had a little flattening in hot weather so I settled on 45.5gr. 2.800 COAL. CCI #200 primer in Redding S die and Competition seater. That CFE223 load in my stock Savage FCP 10 heavy barrel is very very accurate to 1000 and has been to 1200 with excellent results. Varget did well with accuracy but velocity wasn't as good. However temp stability is excellent. If you do try CFE223 sometime remember it spikes pretty quick but gets best consistency and accuracy in the upper nodes in my testing. Your 42.5 load with a little seating depth work may give you a good load with better velocity. Nice video.

[@jamespollard1670]

That 41.5 gr load was awesome . Some conformation shots will be needed .

[@DummyRound]

Definitely have to confirm! I'll be the biggest variable at play so we'll see how they group for me next time.

[@heavyleadenthuasist38]

Looks like you have an excellent load there!

[@DummyRound]

Gonna do some tweaking but we're getting there 👍

[@mckwilly]

awesome Range report

[@DummyRound]

Thanks! I think I got lucky 🤣 Really need to work on my technique....

[@AttackorAdapt]

Id be looking at which cases each data provider used. Anything using Federal, IMI, PPU, or Hornady generally has lower case capacity. I worked up my first 308win load with 4064, with speer 165gr BTSP and its a good powder. I'll try it in 7mm-08, as ive heard it performs well in that as well.

[@DummyRound]

Yeah, that would have helped. 308 and 7.62 can have a huge swing in capacity from brand to brand. Always have to start low and work up because of that. 4064 is one of my favorites, but it's $60+/lb these days and I can't afford that 🤣

[@AttackorAdapt]

@DummyRound def a wise choice. I just looked yesterday at the local, for powder. 6 months ago I picked up 2, 1lb of imr4350 for 64.99 CA each. 119.99CA per lb now.

[@hawaiiangunner]

I am a firm believer in 175gr smk r15 43.1 right in the accuracy node with good speed

[@DummyRound]

If I only had some Reloader 15 to try... stuff is never available around my area, and I refuse to pay HazMat on top of the $70/lb at the current market🤡 However, I do appreciate the tip🇺🇸🇺🇸🇺🇸

[@hawaiiangunner]

@DummyRound so lucky I bought to many. At the time I sworn that it was too much.

[@hawaiiangunner]

@@DummyRound OMG WTF???? HOW MUCH A POUND??? I think it was $23 a pound when I bought it. Maybe less i should go look on the sticker

[@cw2a]

Morning man!! Im gonna load 223 today!

[@DummyRound]

Good morning! I need to do some 223 testing as well.

[@scottnj2503]

Primer cratering... My stock Rem 700 was cratering everything I put in it. NO OVER PRESSURE. Found out the firing pin had rounded out the firing pin hole in the bolt. Had some work done i.e. a bushing installed. Problem solved

[@DummyRound]

I've heard of having to do that before, I'm sure it couldn't hurt anything. Thanks for sharing🇺🇸👊👍

20 inch barrel 175 sierra match king and 45.2 grains of varget gets me sub 1/2 inch groups and 2650 fps

[@DummyRound]

I'll have to give that combination a try one day, thanks for sharing 🇺🇲

[@davidcrane3417]

@DummyRound 45.2 Is the max charge for that powder too btw.

[@DummyRound]

I was going to check when I got around to it. What brass are you running?

[@davidcrane3417]

@DummyRound right now hornady. Was gonna switch to lapua.

[@BlackdogADV]

I’m using a 20” Kriega 1/11 twist. It prefers 168 gr, never found a175 gr it likes. I’ll try that 41.5 range and see how it does.

[@DummyRound]

I need to verify the load but it seems like a good spot to leave it!

[@farmerwayne1404]

Did u ever recheck that 1/2" group???

[@Johnny-jr2lq]

Mmmmmm 175’s I need me some of them

[@DummyRound]

Everybody needs a little Match King in their life!

[@chuckfinley3152]

The factory load is 41.6gr of 4064, buuut, federal gold medal match brass has way less case capacity than other 308 brass. In my lapooooah I need something like 42.5ish to get the same velocity

[@DummyRound]

I'm going to go again but in some brass I didn't pick up from the mud. Seems like a great bullet and powder combo. I have some N140 I want to try. Supposed to be pretty awesome for accuracy, but I'm not sure how hot it can push the 175s. I can only go out to 450y if nobody else is at the range, so I don't really need any extra velocity, anyways.

[@timtrax918artisan8]

you cant disregurd a a flyer unless its a rail gun

[@timtrax918artisan8]

actually not thenn as its part of the average

[@DummyRound]

it's on the paper, so it counts!

[@kaseyowens3065]

Does anyone have info on m118LR loads? I have found that the IMI "7.62 match" version of that particular loading shoots exceptionally well in my rifle, so I have set out to find what powder/primer they're using.

[@DummyRound]

I'm not certain but it probably varies between Reloder 15 and/or a proprietary powder from Alliant, since Vista owns that pile of companies. But, I'm just guessing based on very little research. Thanks!

[@DummyRound]

But, if you're reloading, then you can find any powder suitable to hit the velocity you want with that bullet and go from there.

[@rickm4295]

What is the barrel length ? Is this an AR platform ? Im on this exact mission but i dont have a chronograph.....tough. I have a Remington 700 SPS tactical 20" barrel 1-10 twist. I have a lights out load for 168's but it just isnt good after 600yds, really...I want that 800 -1000 yd 12" gong , lol

[@DummyRound]

22" barrel, 1-10 twist bolt gun. My range only goes out to 300 :(

[@VitoBb1978]

Your 42.5 load seems to be the most consistent. Your using some very good components for sure, are you using the COAL method. ? If so I would recommend using the CBTO method, this will really fine tune the bullet to your chamber. Good luck

[@DummyRound]

I am using OAL to measure at this time. Just got a new micrometer seating die so we can try seating depth tests. A comparator set is on the list of things to add to the bench as well. More to come! Thanks 👍

Wishing you all the best with your load development.

Sweet, I have most of these components minus the boolit weight and primers of course.Crap! I need to do a load data book like that. Dude if this was done at 100 yrd, what u talking about being a crappy shit? I've seen high speed dudes that shot crappier! Don't cut off your chicken pecker, you ain't no slouch.

[@DummyRound]

Ha, thanks, Tim! I just don't have a very good set up on the bench, as far as a rest and bags, so I feel like anything on paper is either my fault or total luck. I'll get better and upgrade my gear soon here enough. I appreciate it!
