So put the scoped muzzleloaders with the rifle season and the keep the scopeless muzzleloaders in the muzzleloader season. The next thing they'll go after is the long range scopes. Game & fish need to figure out seasons and change them instead of restricting equipment!
I've killed moose,bears, and deer with a 50 cal with a TC Encor, 209 Blackhorn powder, 250gr sabots. Center punched a bull moose and stood for about 30 seconds and fell over at 100 yards. Plenty for elk.
This might be a little off subject. Sorry, don't know enough about gunsmithing but, if you do convert it or get rid of the 6.5-300 I would buy any brass if you have some. Thanks and good luck.
Cannot use any part of a vehicle as a shooting rest in Wyoming private or not, and cannot shoot from or across a county road. You can however step off the road several feet and shoot on that side of the road, not across it.
