What horrible place do you live? Muzzleloaders aren't even considered firearms under the law here in the US and, God Willing, they never will be.
I live in New Zealand where , to be able to own and use a firearm we have to have an individual firearms licence , handguns have to be registered and only used for target shooting , Semi auto centerfire rifles are banned except on very hard to get permits . All firearms have to be kept in approved secure safes or racks , ammunition has to be kept locked and separate from the firearms . The only firearms which don't need a licensed owner are antique muzzle loaders .
The laws regarding firearms ownership and use have become very restrictive since an Australian took advantage of our then firearms laws to murder 51 Muslims and wound 40 more . Knee jerk reactions by the Government re this have done us firearms owners a lot of harm .
On the other hand we don't need licenses to hunt Deer ( 7 species ) Goats ,Himalayan Tahr European Chamois , wild Pig , rabbits , hares , Canada geese , there no restriction on seasons , sex, number , firearm caliber , firearm type ,we can use suppressors, night vision , spotlights ,helicopters etc, all we need is permission of the land owner .
So the way I see it we lose some but we also win some .
The only thing which stops me shooting deer with a muzzle loading rifle is the hot mid summer dry weather fire risk we are experiencing at present .
