Back in March, 2005, there was some discussion regarding the Alliant Reloader 7 data for the .44-40.

To continue........
I did eventually try the 240 gr. cast bullet Alliant load of 23.5 grs. in my '73 (1882) .44-40. It went 1,170 f.p.s. in my rifle's 21" barrel. At 50 yards, the group was just under 1 3/4" with all bullets printing nice round holes in the target even in the slow 1/38" twist barrel.
In a friend's 24" barrel it was almost 100 f.p.s. faster at 1,266 f.p.s. which is close to Alliant's published data of 1,290 f.p.s.

A capacity load of RL7 does a nice job of duplicating black powder ballistics with good accuracy in the vintage .44-40.
