I’m getting down to the end on my project rebuilding a badly abused American Knight 50 cal. Lapping the barrel got it to shoot OK, so I’m just fine-tuning whatever variables are left. I’m considering doing a clean-up on the muzzle crown using a brass muzzle crowning lap and 600 grit to recut the crown just enough to get back to a clean exit hole.
The muzzle is worn and the rifling and lands are not perfectly aligned at the end of the barrel.
It may be unnecessary: I don’t know if a saboted bullet needs a perfect crown. I’d appreciate input from the experts here.
