View Full Version : Hand loading for .308 Garand

One of my Garands is a 1943 SA Garand in which the prior owner had rebarreled and chambered it for .308 Win. I bought a Hornady single stage handloading kit the other night plus all the components to load new brass in both .30-06 and .308 for both Garands. The Hornady handloading manual has a separate M1 Garand section, but it consists of loading data that is specific to the M1 chambered in 30-06. So, the problem I have is that although I have all the data in the Hornady manual to load for my 30-06 M1, I have no idea of what grain weight of powder / bullet gr. combination to use for handloading new brass for my .308 M1. Thus, my question is whether anyone knows what powder gr. / bullet gr. combination(s) I could or should use to load for a .308 Garand? Or, should I just use the loading data listed in the Hornady manual listed for the M1 in 30-06 for the 308? Any advice will be greatly appreciated!

DO NOT USE THE RELOADING INFORMATION FOR THE .30-06 FOR THE .308!!! Do a google search and you will find a lot of different options. Sorry but I do not have my information with me right now. I'm sure someone will chime in with there favorite pet load.

Thanks,

Tom

The Hornady manual also has a section called "308 Winchester Service Rifle." These loads were developed in an M1A. The powders look appropriate for an M1. Start at the bottom and work up.

rcolarco is right on the beam.

If you load for an M1A service rifle, usually 4064 or H4895, you won't have any issues with op rod damage or accuracy.
Generally speaking, the gas port on a 308 Garand is .086 instead of .0785 so function is accounted for.

Load for a 308 Service Rifle and have fun.

This is what you want.

You can compare the following to what you find in the manual. The first load was given to me by Don McCoy when he built my rifle back in 1984. They work in both my M1 and M1A.

168 grain Sierra HPBT, 41.5 grains of IMR 4895, LC brass

150 grain HPBT, 43.0 grains of IMR 4895, LC brass

Thanks everyone. I hadn't come across the 308 service rifle / M1A page yet in the Hornady manual, but I'll also be reloading for a NM M1A, so this will make things less complicated.

Regarding CDRT's post, I was thinking about using the Hornady A-Max or V-Max match bullets. Are the Sierra match king HPBT's that much more accurate? Also, are the Sierra HPBT's legal for CMP JCG or service rifle matches? My understanding is that military ball is simple FMJ and would therefore exclude HP ammo. Thanks again.

I don't know about the legality for competition, but all the bullets you mention shoot well. Which shoots best in your rifle is up to the rifle. I load the Sierra and Hornady 168 HPBTs, and I cannot tell the difference. Both shoot better for me than the A-Max, but your results may differ.

Varget is the powder I bought the other night to load for both the 30-06 and 308 upon the recommendation of the Cabela's salesman.

The Hornady Manual also has the data for 7.62mm Service rifle, USE that ; the data below by jjj0311(he sound like a jarine to me), is very good data.

You will need to read the specific program for the match you intend to shoot. Most "big" CMP JCG matches require you to shoot whatever ammunition is issued by the match sponsor for the match. Most club matches shot to CMP rules allow, or may even require, that you bring your own ammo. In that case, it's "any safe ammunition". Bullet choice is yours.

I was told yesterday that for the Texas state JCG championship (held at Terrell, Texas last weekend) that they issued .30 ball ammo, but that it was issued mixed between different manufacturers and even those of the same manufacturer were of different lots.
