Default Looking for IMR 4895 reload charge

Hello All,

I'm looking for reliable reloading info for the Garand using IMR 4895 powder, CCI 200 standard large rifle primers, HXP brass and the following 150 grain bullets:
  • Hornady FMJ/BT # 3037
  • Sierra GameKing FMJ/BT # 2115
Anyone got a good load range for that?

Thanks in advance.

You have to work up the load for your rifle. Load for the bullet weight using data in your manual. Who made it doesn't matter.
The Hornady manual has an M1 specific chapter. Hodgdon gives 49.0 to 53.0 for a 150.

sir, the Hornaday book, 7th edition, list H-4985 (not IMR) for a 150.
C.O.L 3.185
43.2g @2400 fps
44.8g @2500 fps
46.4g @2600 fps (this is listed as max load )

The IMR and the Hodgedon are very close to each other. IMO these numbers will get you in the ball park. many of my friends use 45.5g's of IMR with a 150 with good results. the info that sunray posted above (IMO) is for a bolt gun and NOT for a Garand. I have used the the hornaday BT-FMJ bullet a lot, and I really like it. I think you will find out you will be in the 45 to 46g range on the charge, but I would not go past 47g's if it was me.
The Hornaday book lists both "H" and "IMR" 4895 for the 168g bullets, and the charge weights are all most identical . HTH.

Additionally, do not forget to drop your loads a bit if you are loading military spec brass (HXP, LC, TW). I think it's generally agreed to drop it by 1 full grain.

I like the Hornady load data. I've had nothing but good results. I only shoot 100 - 200 yds, so I generally stay on the low side of the range, save powder and less wear on tear on the rifle and my brass.

The 168 grn Hornadys are great projectiles. I've also used the 155grain FMJBT with success, but I'm currently working through some 147grn Russian resized .311s "Enhanced Penetration" projectiles. I'm getting roughly the same performance at 100/200 as the Hornady 155s...

Good luck, measure twice, weigh and verify your powder loads often. When I first started, I loaded 500 rounds UNDER 10 grains due to calibrating my cheap Lee balance scale incorrectly. I've since moved to a digital scale, which is better but has it's own problems.

I check each loaded case with a headspace case gauge. Invaluable tool in the reloading arsenal.

Toki--It's generally agreed that 30-06 military brass weights are the same as Federal and RP brass. The new Hornady cases are light at 180grs. Case weight is not a factor with the mid range loads used in the M1. Good Shooting.......

Totally not necessary for the '06. That information applies to 7.62x51 brass. That being said, I run 49.0gr of IMR4895 behind my 144gr FMJBT bullets, so anywhere's from 48 to 49 grains will work fine with 150 grain bullets.

Cheers! That's good to know. Been hammered into me by forum members here to drop 1 grain. Someone also said "10%", but I thought that was absurd. That would translate into 4 - 5 grains LESS when using military brass!!!

The classic load for M2 replication is 49grs of IMR-4895.

New to this M1 30.06 reloading but isn't the max charge of H4895 46.4? My reading here says that IMR and H are close enough to use the same data so can one assume thent that this "classic load" of 49 grains exceeds the recommended charge for IMR 4895?

The military spec's for M2 Ball is 150gr bullets @ 2740 fps @ 75 feet from the muzzle. If you use a chronograph at 10 feet from the muzzle you will be right at 2800 fps plus or minus 40 fps.

The powder range is up to 52 grs of 4895 as long as the velocity is within specified limits.

Over the years of shooting surplus 4895 and various lots of IMR 4895, 49grs has been considered by the Garand shooting community a safe replication load for M2 Ball loading.

If you want to know if your pet load duplicates M2 Ball spec, shoot some M2 military ball over a chronograph, then using IMR-4895 and 150 gr bullets, test loads over the chronograph until matching fps is achieved at the muzzle. You will then have the max load for your Garand. (With that lot of powder)

Remember you are not protecting your rifle from chamber over pressure but from the operation rod being bent from too much pressure at the muzzle, which will accelerate the rod too much and cause it to be bent when it slams into the receiver. 49 grs of IMR-4895 is several grains shy of max published 150gr bullet loads in a bolt action rifle.

If you want to push your Garand to max pressure for the chamber, you need to get an adjustable gas plug and move your powder selection to 4350 or 4831. Either will get max velocity with a full case, but the adjustable gas plug must be used to protect the op rod.

Good luck and have fun loading for your rifle.
