375 Win Winchester 94 XTR, 235 grain Cast w/GC, 19.9 grains IMR4227, 2.95 MOA (I cast these)
375 Win Winchester 94 XTR, 237 grain w/GC Cast, 19.9 grains IMR4227, 3.89 MOA second group - I probably weighed these bullets and they were heavier than expected.
375 Win Winchester 94 XTA, 287.5 grain w/GC Cast, 21.7 grains 5744, 4.21 MOA: I believe that this was with Pete's projectiles sized to .377 - these bullets were wieghed.
I bought a couple boxes of cast from Montana Bullet Works (Lyman 280 Grain FN-GC) - one box .376 diameter and one box .378 diameter) and a couple boxes from Pete's projectiles. (288 grain 375449) also with gas checks - One box .377 and the other .378 diameter.
Other loads with jacketed.
375 Win Winchester 94 XTR, 255 grain Barnes, 34 grains RE 7, 2.21 MOA
375 Win Winchester 94 XTR, 200 grain Sierra, 39 grains 1680, 2.04 MOA
375 Win, Winchester 94 XTR, 200 grain Sierra, 33 grains IMR4198, 3.47 MOA
This rifle has not been out much. It's fairly new to me. It wears a Lyman Steel aperture rear sight and factory front sight. I'd imagine the group size would have shrunk if I had a scope on the rifle, but I don't much favor scopes on lever rifles.
Have you looked under the Big Bore Lever Forum?
