Loading IMR 4227 under 30-30 SWC's
I just put together some GC'd, 173 grain, Lyman 311041, SWC's, in 30-30 caliber, over IMR 4227, at an expected 1,700 fps, in accordance with the Lyman No.4 Cast Bullet Handbook, which is a "small volume charge" in that case. I am wondering how powder dispersal may affect accuracy?
If the IMR 4227 is good, it offers a "mid-range" of the published charges, and 2X the opportunity to shoot more from an 8# can, notwithstanding a multitude of pistols that will also tap that can for its resource.
These rounds are only the start of accurizing multiple powder opportunities in a pair of Marlin 336's, with Win 748 being a proven contender.
