RE: help me choose my first muzzleloader
First off welcome to the forum...
As for a choice of rifle. That is a very personal decision. Whether the plastic sights will break.. well I have plastic sights on my CVA Staghorn Magnum and they broke the very first day I had it out. All it did was bump the wall as it slide a few inches. But I fixed that. And CVA sent me a new sight.
The Remington Genesis.. that I am sure would be a fine rifle.
Have you considered a NEF Sidekick? They are made by Marlin Rifle Company/Harrington & Richardardson through New England Firearms. I am not sure of the sight they have but it is a Tru Glow Fiber Optic. Also they have some excellent reports of out of the box accuracy. They do require a primer holder. The others do not.
Any of them would do the job. Maybe since you only want to see if you like this or not, get the cheapest. The Wolf has been getting some excellent field reports. That might be the way to go.
