RE: Most accurate, Worst, Favorite out of the box Muzzleloader.
Well my experience with inlines has been limited to 2 - a CVA Optima Pro when they first came out and a Remington Genesis. Of these 2 they were both comparable in accuracy with a slight edge to the Genesis.
Most of my muzzies are sidelocks and all are T/Cs. One Renegade and 5 Hawkens. I would say that my one 50 cal Hawken with the GM LRH barrel is probably the most accurate including the Genesis. The 45 cal Renegade and Hawken with GM barrels are a very close second.
My 'worst' shooting ML is my T/C Hawken flinter with the GM LRH carbine barrel. And even though I consider it the worst, it ain't bad and I carry it most of the time during PAs primitive season in Dec - Jan.
