For the small amount of money you'll have in it, I think it's a "good deal" for you.
Like Necchi wrote, there's a "learning curve" and you'll have another couple of hundred dollars to get all the other "accessories" so vital to having and shooting a muzzle loader, but even at that, you'll still have very little invested and should be able to recover your money spent if absolutely necessary.
However, I'm confident that you'll
LOVE it... and being a bow hunter, hunting with a muzzle loader is the "next step" in using different hunting instruments. A 50 caliber ML rifle will increase your game-taking range from a maximum of 30-40 yards out to as much as 100 yards if you "push" it, but 75 or 80 yards would be more "comfortable" with iron sights on deer-sized game.
Just try to have FUN in going through the same "learning curve" that all of us have had to go through. You'll find there are as many opinions about how to do something "right" as there are people offering those opinions.
Buttttttttttt... believe it or not, you'll come through it a much wiser, better hunter. And a .50 caliber ML rifle is more than "enough" rifle for deer sized game. You can also take small game with a .50 caliber patched ball... you can sharpen your shooting skills & aim on squirrels and rabbits.
If you can shoot 3 to 4-inch, 3-shot "groups" at 50 yards, that's accurate enough for deer at reasonable ranges.
Most Traditions .50 caliber rifles use .015" to .016" patches together with a .490" soft lead ball. I have a Traditions .50 caliber "Shenandoah" with a 33½ inch barrel & a 1:66 twist. Your rifle's barrel will be about 27-28 inches with a 1:48 twist. It will stabilize the .50 caliber balls quite well.
I'd recommend that you attempt to find a "mentor" among those guys who shoot muzzle loaders in your area... someone you can ask questions of and get reasonable, knowledgable answers... someone to show you the "how to's" of muzzle loader shooting.
And don't "sweat" the mistakes... 'cause EVERYBODY makes 'em... and don't smoke around black powder... that's about the quickest way to make yourself REAL "unpopular" among the other black powder shooters.
Start out with
Goex FFFg black powder. Swiss Black Powder is supposedly slightly better (cleaner burning, gives higher velocities with the same load of powder, etc.), but either one will work in your rifle. You can also use the artifical black powders in a percussion cap rifle.
Get the "magnum" percussion caps... they will light off the powder more assuredly... the Traditions probably uses the #11 caps, but check it out and make sure you buy the ones that fit your rifle.
At Friendship, Indiana (home of the National Muzzle Loading Rifle Association) last June, Swiss black powder was $22 a pound, Goex was $14 a pound... a BIG difference for practically the same performance... and Goes is American-made, Swiss is from Switzerland.
Some may recommend you buy FFg black powder, but with your rifle's shorter barrel and your desire to 'work up' the most accurate target load and the most accurate hunting load possible, you're more likely to find it using small increments of powder charge increases, I'd strongly recommend you start out using FFFg powder and work up that target load first.
FFFg powder is faster burning than FFg and generally develops a greater muzzle velocity in shorter barreled rifles quicker than FFg does.
Good luck with your new venture...
Strength & Honor...
