tscott,
You bet. Cutting a rifle down to make it handier makes sense. I have a Handi 30-30 cut down to 18 just to make it easier and faster handling in the brushy river bottoms and out the truck window (Off road only of course!). And I have a 223 Ultra cut to 16.5 inches for the same reason. Both have shown the same accuracy as before I cut them down. And the slight loss in velocity has been made up by being quicker to target.
I'm going to have the 45-70 cut mainly because not being a black powder or competition shooter, I just do not need or want that 32 in barrel. With the BC stoc it looks very "period", but I'm going to have it a modern laminated stock. Also I get rid of that dove tail. It will be scoped so sure don't anything to get hung up. I know what it's like to carry a 26 inch, and feed back has me thinking about leaving it at 28. Due to the recoil these puppies can generate, I might appreciate that 28 inch tube.
