.44-77 PP bullets.

[Kurt]

Jim,

I don't have a .44-70 reamer but I have a .44-75 Ballard reamer on a .45-2.5 case that could be used to short chamber and cut a recess for the rim. The full size 2.5 chamber holds the same as the .45-90 around 82-3 grains and it's a very good shooting caliber that would make a fine hunting caliber as well as a silhouette rifle and long range.
The .44-77 Shiloh you shot with the standard chamber has a 30" light weight 19 twist barrel and it's 1.040" at the breach and .900" at the muzzle and comes in right at 10# The trigger breaks just under 3#.
The .44-75 Ballard is the most consistent shooter at 200 yards with 5 shots under 3".
