Just got back from the range with my new LabRadar chronograph. Both these loads were shot using my 45 Colt S&W Mountain Gun with a 4” barrel. Both used Alliant’s Unique powder. And both used Berry’s 250 gr bullets.
A) Full length 45 Colt brass with 9 gr of Unique: 900 FPS
B) Starline Cowboy Specials brass with 6.7 of Unique: 750 FPS
I got the load for the Cowboy Special by using data from 45 ACPs.
Do these results (performances) seem a bit low?
