Had it out to the range yesterday for the first time.
This thing is a riot! Took the chronograph and tried out a bunch of different loads using Accurate TCM powder (Midway was closing it out at $17/lb and apparently it does great in .41 mag) and 240gr Keith SWCs and 215 SWCs, all hard cast from RimRock.
Attached File15.6 grains was the winner for the 240 grain bullet. Next step up was the max load, but the SD got wider, and not much more speed. 1250fps average, 833 ft lbs/energy.
Attached File17.5 was the winner for the 215 grain bullet. 1357fps average, 879 ft lbs.
Attached FileMy max 215 gr load, about .2 grains under published max, had a few well over 1400 fps, with a max of 1474, but the SD got a little wild, with the lowest being 1384. Still, no pressure signs.
I’ll spend more time trying for tiny groups on the next trip. Yesterday all shooting was offhand at 20 yards, and all loads shot pretty well, but clearly not what this thing is capable of.
