Looking to start muzzleloading, I've been hunting many years but never with a muzzleloader, hoping to extend my huntin season. Looking to buy an entry level CVA(limited funds), using Pyrodex with powerbelt bullets. My question is what caliber (45/50)? Most of my hunting will be whitetail/mule deer. However, do plan a elk hunt in the future (after alot of practice/experience). Leaning toward a removal bolt model, any other tips, suggestions, etc.
