| I have an M1 Garand rifle in .30-06. What is a good powder? I like a full case rather than a half empty one in a finished cartridge. |

M1 is picky with gas pressure, stick with IMR4895 or IMR4064.

Make it sticky M1 loads (Courtesy of the NRA) Recommended .30 caliber M1 loadings from the NRA All loads listed are max loads, reduce by 10% to start. 147 - 155 grain FMJ or HPBT bullets IMR 3031 - 48.0 grains IMR 4895 - 49.0 grains IMR 4064 - 50.0 grains W748 - 48.0 grains AA2460 - 49.0 grains AA2520 - 51.0 grains AA2495 - 50.5 grains H4895 - 49.0 grains BLC-2 - 49.0 grains H335 - 49.0 grains RL-12 - 48.0 grains 165/168 grain FMJ, HP or SP bullets IMR 4895 - 47.0 grains IMR 4094 - 48.0 grains AA2520 - 47.5 grains AA2495 - 47.0 grains H4895 - 47.5 grains BLC-2 - 49.0 grains H335 - 47.0 grains RL-12 - 44.5 grains 173/175 grain FMJ or HPBT bullets IMR 4895 - 46.0 grains IMR 4064 - 47.0 grains AA2460 - 46.0 grains AA2495 - 46.0 grains H4895 - 47.0 grains BLC-2 - 48.0 grains 180 grain FMJ, SP or HPBT bullets IMR 4895 - 43.0 grains AA2460 - 46.5 grains AA2495 - 45.5 grains H4895 - 44.0 grains BLC-2 - 47.5 grains RL-12 - 41.5 grains Comments These loads only duplicate military spec. velocities for the given bullet weight, using commercial cases and powders. If you are using military cases, drop all charges by 2 grains. If you are looking for accuracy, drop all charges by 1 grain and work up .2 grains at a time. Additional M1 loads are listed in Hornady's 7th ed and Accurate 1st and 2nd ed handbooks |

Quoted:
Remember those loads are full military power. I enjoy a somewhat lighter load. Of course your mileage may vary.  YES.........and then there is the "standard advice" about reducing loads to start and warnings/cautions about, switching components, military brass, bullets aren't all the same, etc.......... Not to mention that...........most will find that the most accurate, will more than likely NOT BE the "full power loads." Then, as you pointed out...........YMWV. Some people expect to get superior results by just following someone's load data recipe. Aloha, Mark |
