Gentleman I'm curious about the 44 cal cartridges you are using and are available either as head stamped brass or easily formed. Both bottle necked and straight. I see 44-70, 44-77, and 44-90. I'm contemplating a 1878 Sharps from C Sharps arms and want to play with a different cartridge. I'm currently shooting 38-55, 40-65, 45-70, and 45-90. What would be recommended as to barrel length, twist rate, sights. I'm also planning on dilled and tapped for MVA Malcomb scope blocks both 7 1/2" and 17" centers. Thanks for your time
