    What I use may not work with your M1.. I use 168 gr bullet and 46 gr IMR 4895 powder, #34 CCI primer.

    I prefer the IMR 4895 series of powders in my Garands. Accurate Arms AA2495 is a copy of IMR 4895 but stupidly they call it something different and confuse everyone. Accurate Arms told me it duplicated the 4895 pressure. When it was less than IMR 4895 I shot at least five kegs of the stuff through M1’s and M1a’s. I could not tell any difference on target or over the screens. I am shooting H4895 in my M1a’s, I have tried AA2520, a ball powder. Accurate Arms told me grain for grain it also duplicates the IMR 4895 pressure curve. It is a lot denser than the stick powders and a lot messier. Leaves a lot more residue in the gas system; still it shoots well. I cannot say that the better throw uniformity you get with a ball powder really means anything on paper.

    I have buds who love IMR 4064, but it does not throw well. For them it does not matter as they weight each charge. That takes too much time for me.

    A bud who placed very high in every Garand match he shoots, he loads 46 grains IMR 4064 with his 168's.

    I shot the 168 out to 600 yards with great success but when the 175 SMK’s came out I used those at 500 and 600 yards.

    My standard load out to 300 yards is a 168 grain Nolser/Sierra/Hornday, 47.0 grains IMR 4895, military cases, CCI #34 OAL LT 3.30".


    You can cut the load by a couple of grains and it will still shoot well.

    November I ran a primer test with all the primers I had around the house. I wanted to see how Wolf and Tula 7.62 did. Those primers shot very well and are considered "Mil Spec".

    You absolutely do not want to use primers that are "more sensitive" in Garands due to the risk of slamfires. I recommend CCI #34, then Tula7.62 as these are sold as mil spec primers. I do not recommend Federals in Garands/M1a's as these are the most slamfiring primer on the market.
