Personally, I think, what you describe is a open breech. Therefore, not a muzzle loader! But what is the point. Inline, sidelock, or flint'r,are essentually the same. All loaded from the bussiness end!! As too, my original post. I don't see many touting match locks.
As for deer herds, they are in record numbers(at least here, due to mild winters the last 2 years), and are paying for it with natural diseases taking it's toll.
I still don't see the need for bickering between traditionalist and modern. It's fine to have your opinion,which I try to respect, but quit whine'n please. The in-line shooter's aren't hurting you. Yes there are hunters out there, but more deer also. Granted aliitle more crowded, but no reason to belittle the next HUNTER for techincal reasons.
