Default M1 Garand load

I am using Hornady 150 grain FMJ-BT and IMR 4895. I have settled on 49.0 grains for this load. What velocity is safe for the M1?

2700 fps is safe. When I load that powder bullet combo, I load 47.5. That's what shoots best in my rifles. Start around 44gr or so and work up and see what works in your rifle. If you are only shooting 200 yds and under why put un-needed wear on your rifle? Plus saves powder, which means more shots per pound.

I use the exact same bullet, but I load it with 45 grains of H4895. It's a great all purpose combination. And I don't shoot further than 250 yards anyway.

(And it costs about .08 cents less then if I buy new from CMP!)

49gr may be fine but it's well above any posted MAX for Garand loads with a 150gr bullet and probably much more than you need to drop for best accuracy. You'll be buring more powder and money than needed for an accurate load. Velocity has little to do with determining the appropriate loading for Garand loads. Published data does but most of that is very conservative. I probably would never drop 49gr of IMR 4895 for a Garand load. Published data tells me about 47gr is MAX. I have dropped 49gr and more for a bolt gun load but I, personally, wouldn't run it in my M1.

Starting at above MAX published data is a poor way to begin your loading experience with Garand ammo loading. I would strongly suggest starting about 45gr and working my way up to find the most accurate charge for the range you will be shooting at. When I was using IMR 4895 I found 46.5gr at 2.9" OAL with a FMJBT to be my most accurate load. Then I discovered how well 46-46.5gr of IMR 4064 powder and 3.30" OAL shot in my M1 and I decreased my groups by 1-2 MOA.

IMR 4895 @ 49 grs under a 150 gr bullet is perfectly safe for a M1 Garand. It is a classic M2 Ball duplication load.

M2 ball duplication efforts should have IMR 4895 @ less than 52 grs of powder pushing a 150 gr bullet @ 2800 fps + or - 50 FPS.

Gas volume which will be indicated by charge weight is what pushes the op rod.

My current lot of IMR 4895 @ 49 grs gives me 2800 fps, this is less speed than my Greek
Ball by about 50 fps.

So please feel free to safely shoot 49 grs of 4895 in your rifle under a 150 gr bullet, it will be a great load.

+ 1 Larry on the IMR 4064 loads. That's about all I run anymore other than H4895

Start low and work up. That's a standard and very proper reloading technique that's worked for decades. There no reason to drop more powder than you need to for accuracy and no reason to simply duplicate M2 Ball loads, just because, as your starting point. Standard M2 Ball doesn't shoot all that well in all rifles so if you just want a load that provides an "average" level of accuracy load up a duplication load and shoot it in all your vintage 30-06 rifles. If you want to likely achieve a more accurate load, probably by dropping less powder and saving money too, work up a load by changing charges, and OAL as well, along the way. Military ball is also neck crimped and uses military primers. I haven't crimped or used mil spec primers for Garand loading in 10 years and saved time and money as a result with nothing but positive results.

49gr IMR 4895 will result in a hard recoiling, fast, average M2 load. If that's what you want to achieve....go for it. Better accuracy can be achieved with a little time and effort and your shoulder will probably appreciate the results too.

And it meters 100% better out of the powder measure too. Varget too.
