I run 90 grain 2F with patched ball in my 54 for hunting. Targets generally get 60 grains for economy and recoil. I run a damp patch between rounds and I can fire indefinitely without the barrel getting tight.
I'm glad to see someone running a 54 cal with a carbine length barrel...
My response was in 'jest' also! I know there are some out there with 36-38" but I figured I didn't want to have to use a set of wheels to tote the thing around! I believe 34" will suffice for what I want to use it for aka sitting at the bench in my back yard or in a deer blind in Kansas! I'm looking forward to it! No cases to clean, no cases to size or prime! I've been shooting Sharps now for going on 20 years and I'm feeling 'burnt out'....if you know what I mean!!
