I have a cva scout 45-70 conversion along with a savage centerfire action smokeless. Both are fantastic. One uses an out of date Hankins style ignition and the other uses arrowheads system. The savage can be pushes much harder than the breakdown style guns. But a rifle that doesn’t use a barrel but can be pushed harder than my savage. Pretty sure my barrel is a pacnor. Much better than using a black powder substitute!
