H-335 powder for M1 Garand (30-06)

GWV · June 7, 2010, 06:41 PM

I have a copy of MASTER PO'S M1 loads from the NRA, and the recommended .30 cal 147-155 grain load using H-335 powder is 49.0 grains. I have a whole mess of pulled military M2 ball on hand and would like to try this load for shooting around 100 yards. I am using this powder in my AR-15 and it shoots great with 55 grain hornaday V-Max bullets. My question is, has anyone used this recommended load and if so, how accurate was it ? I don't want suggestions on different powders, just some results on this load.

PLEASE VERIFY THIS INFORMATION.

I believe M2 Ball ammunition used IMR 4895. I would suspect load data for that powder would be how you want to work up this load.

PLEASE VERIFY THIS.

H335 is slightly faster than H 4895 which is slightly faster than IMR 4895.
The problem with reloading for the M1 is excess port pressure caused by using powders too SLOW burning, thus having too much pressure at the gas port. Using a slightly faster powder such H335 as will not cause this problem.
Start low & work up carefully. Don't damage that ole warhorse.
I will suggest however, that IMR / H 4895 is and has been a favorite with the M1 for many years. IMR 4064 is also used with great success. Nothing faster than 4064 is recommended for the M1. (although many have used slower powders and gotten away with it, or used an adjustable gas plug.)

Thanks guy's, I suspected exactly what you have brought to my attention and will use the powders you suggest.

rjrivero · June 7, 2010, 07:44 PM

I guess I'm confused.

Do you have M2 Projectiles on hand or M2 pulled powder on hand?

I was under the assumption that you had a bunch of M2 Powder on hand and were looking for load data on that powder.

I have pulled M2 Projectiles

The hornady manual section on Garand loads list 46.4 as the max for the 150 gr bullets. Looking at the book about 43 grns would give you the same volicty as the military ball.

I cant say for sure, I havent tried it.

Like others said, I use 4895. It was developed for the Garand. 47 grns using 168 SMKs sure shoot nice in my Garand.

The original M2 ball ammo was loaded with 50.0 grs IMR4895 powder. Muzzle velocity was measured at 78 feet from the muzzle and was suppose to generate 2740'ps. In later years, the military started specing their own powders and one that was used for loading was WC844. You know it by the canister name of H335 or 748. There is also a WC844T that burns significantly hotter and is used in tracer ammo for reliable ignition of the tracing compound. So yes, you can use H335 and you should not any timing issues with the op rod or damage from poorly timed ammo pressure curve.

Huh. I've been loading 47gr of 4895 with the 150gr pulled bullets. I keep getting different opinions as to charges for the Garand...

My Lyman manual shows the 150gr SP with 46gr of 4895 at 2680fps.

Kraigwy (and the OP) was referring to H335 powder, not 4895.
