RE: 385 gr. grat plains bullets ?
Most bullets - even in an entry-level ML - with proper powder volume will shoot well enough to hunt at 50 yards. For an inline, that range is not difficult. The true test comes at 100 yards & my fast twist barrels do not shoot any sub-400 grain conical well at 100 yards. I tested 13 different conicals in two fast twist Mls from 245 grains to 385 grains with no hunting accuracy. I had to boost conical grain size to 420-460 grains for better success. Your Great Plains bullet in 385 grains was developed to perform best in slower 1-38/48" twists. Congrats on your 50-yard success.... but if that bullet fails at 100.... try a bigger conical.
