Remember the cast-bullet loads I tried in the M1 Garand?

Last time went to the outdoor range I finally remembered to take the tripod and set up the Chrony: in my rifle, 35.0 grains of IMR4895 over a 150-grain gas-check bullets equals an average 1950fps. No function problems, and the only sign of lead fouling I've ever found was a couple of specks on the piston face.

I'm going to keep messing with this over time, see if tweaking it will tighten groups a bit. But for what I started this for, a light load for when I can only get to the indoor range, it works fine.
