P.S>>>>>Beginner Inline Muzzleloading Advice
Know matter what Muzzle Loader you finally buy, you do need to break them in some what like a rifle.
I suggest you load and shoot no more than 2 (twice ) between cleaning for the first 20 shots at least! (be sure you remove and clean your breech plug also between cleanings) I use TC bore solvent to clean , apply just a dab of TC Natural Lube Bore Butter on the breech plug to keep it from seizing up on you(or it will become hard , or almost impossible to remove breech plug) not to much or will obscure flash hole!
And use "lead conical bullets for break-in" (for 50cal. .....TC\370 maxi-balls....)
Start with 90gr. Pyrodex to start with for break in, 20-30 shots!
I know its time consuming, but if you want your Muzzle Loader to shoot accurate for a life time! "its well worth it!"
Then if you opt. you may shoot Sabot's , but will require even more cleaning because there copper jacketed.
I personally shoot TC\370 maxi-balls, 115grs. Pyrodex.....
Kick's like a Mule! but to each his own!
