In my 1895SBL, I've settled on 2 bullets that shoot to the same POI. One is the cast performance 405gr wlngc over 50grs of Varget. The other is 45grs of reloder 7 and a hornady 350gr FP. The 405gr does an even 1500fps out of my SBL. I have not chronied the 350 hornady.

Some say Varget is to slow for the 45-70, and I do get some unburned powder. However, I get very good accuracy and 1500fps and a 405gr hard cast will do anything I need it to. I have not killed any game with it yet. It's also fairly easy on the shoulder. I tried max loads just because, and the recoil in my opinion is not worth the extra FPS..
