Grouchy Spike Posted March 7, 2019 Share Posted March 7, 2019 This load for the M1 was developed by Dusty Boddams. It's not listed under a specific heading in this section, although found in other threads, so I thought that I'd start this thread and make it easy to find the recipe. It is 35.8 gr of IMR 4895 and 170 gr Sil GC 0.310” Cast Bullet by Norm Purcella, Winchester LRP. And the Winchester primer or the CCI #34 military primer. He said that the load could be adjusted slightly up or down to operate a specific M1 rifle AND find the sweet spot in group size. Another Garand shooter, Marshal Willy, shared this load using his favorite power IMR 4198: It is 35.0 gr of IMR 4198 and 150 gr cast bullet.

Grouchy Spike Posted March 9, 2019 Author Share Posted March 9, 2019 Goatneck, does not the floating firing pin in the M1 dimple the primers when the bolt is closed? I thought that use of military spec primers would eliminate the possibility of an out-of-battery discharge. Winchester primers are an acceptable substitute I am told.
