Looking for some of you sidelock guru's. I have a Charles Daly 50 caliber Hawken that I love to hunt with. It has a 1 in 48 twist barrel. I really want to be able to shoot pure copper HP's through it accurately. The sabots I was shooting Through it have been discontinued or I just can't find them. It doesn't shoot others well at all. I would love to put a 1 in 28 twist barrel on this rifle if possible. I just don't know if that's possible? Not sure if all hawken style drop ins will work or what? Thank you for any guidance?
