Toby- my .375 shoots very well indeed with a full case of Trail Boss along with a 310gr. flat nose case bullet, producing a velocity of 1,350fps.

This is slightly higher speed than a 300gr. .38/55 load with black powder - it's a "go-pow"plinking load, no recoil and low noise that will handle any game close in, up to moose and elk.

The only problem I see with most .375's being the Good For Everything, is many people today prefer lighter guns than the typical .375.

This is also try of the 'modern' muzzleloading community where the participants will sacrifice the steady offhand shooting stability of a nice 10 pound rifle, for a lightweight gun that cannot be held steady, due to poor or very little muscle development, I assume.
