Why not just get onna those fancy shootin sticks, ya know the ones that collapse and weight all of a 1/2 pound an fit in yer pocket? An practice with that.
Heck a nice straight cedar branch with a fork and the bark peeled can even double as a walking stick. Dustin did that for a full year with his .50 BP ML.
That's a nice way of sayin I ain't a proponant of choppin barrels, esp for here in Mn and west,,
I think alot of what's going on nowadays about short barrels, is folks trying to"militerize" sporting guns,,40 years ago it was "sporterizing" military guns,,
