At expected velocities, especially if cast bullets are used, the .375. While the difference is not great.....at low velocities or a non-expanding bullet.....the larger diameter bullet is simply better for hunting big game! IMO memtb
Considering that they had micro-groove rifling, will Marlin 375s work well with cast bullets?
Now, you went above my pay grade! I was simply judging on bullet diameter! That said, while the micro-groove does require some considerations.....they perform very well with cast bullets. Go to the Cast Boolit, yes “Boolit”, forum....there is more information on that site than you can absorb. Lot’s of information pertaining to micro-groove bores! memtb
