Running 44wcf loaded with Trail Boss powder through my Lever Gun

Loaded up some plinking rounds for 44wcf or more commonly called 44-40. 5.5 grains of Trail Boss powder with a 200 grain RNFP hard cast projectile in Starline Brass. Using my Taylor & Company Uberti made Model 1873 with a 20” Octagonal barrel. I’m happy with these velocities for plinking and maybe some use in Cowboy Action shooting as well.
