Are you loading the .375" or the .377" Barnes Original 255 grain bullet in your .375 Winchester?
I have a box of .377" that I bought to load in a Marlin 336CB Cowboy in 38-55 and would like to try them in my Marlin .375. It has micro-groove rifling and the groove diameter is .376".
Anyone forsee any problems in using the .377" bullet in a Marlin 375 or a Win BB94 375?
