You can do anything in the 45/70 that you can do in the 450 marlin but its best with starline brass as starline brass is much thicker and stronger than some of the other brass manufactures. I used to shoot quite a few 405gr JSP loads with H322 @ 1925fps. For hunting I used kodiak bonded and practice I used remington bulk bullets. They shot the the same point of impact.

The garret, and buffalo bore type ammo is all loaded to within the specs of the 1895.
