I have a Model #1 Roller. As such I never bothered with the 7x57 or any other smokeless cartridge.
It came rebarreled in 40-70 Sharps Straight(40x2 1/2) which I have had great luck hunting. I kept that
barrel but rebarreled to 40-50 Sharps Straight to shoot in schuetzen competition. I have shoot several
targets in the 210-220 point range on the German Ring target. All shooting has been with black powder.
A lot of the #1's were chambered in 45-70
