Are you planning to hunt with this gun? If so, the first thing you need to do is check out your state's regulations. Pennsylvania, for instance, only allows flintlocks for muzzleloader hunting season, so buying a caplock there would be a waste. Colorado, where I live and hunt with muzzleloaders, doesn't allow scopes, so you surely wouldn't want to buy one of the inlines that has scope mounts but no sights on it!

After that, it's largely a matter of personal preference. Do you like the looks of the traditional rifles? Do you prefer something more familiar looking and feeling? The fact is that the modern inlines provide no real ballistic advantage over the more traditional-looking rifles, so don't fool yourself into thinking that by buying something that looks modern you'll be getting much better range, penetration, ballistics, etc.

i hunt Ontario, as for regulation i am not sure about them on muzzleloaders. Alothough i do know there are seasons and open for muzzleloaders, but shotguns fall into that class aswell.

Im looking at a thompson centerfire 50cal for my first muzzleloader anyone got expiernce with this gun??? anyone got any other expiernces with any other gun that would be a good learner for a muzzleloader

and Yes i plan to hunt with this gun. take advatage of every season i possibly can

Well, again, the first thing you need to do is become familiar with the muzzleloader regulations where you want to hunt.

Beyond that, Thompson makes fine firearms and though I've never personally used one I'm sure you'd be happy with any of their offerings. In .50 they have both modern and traditional-looking choices, so your next decision is what style you want to go with. I prefer the traditional look, but that's just me. You have to decide for yourself what you prefer.
