the replacement plug is inexpensive relatively, easy to install, just slow down and read the instructions if you have any questions there's videos online how to do it,, I kind of owe where I am today with muzzleloaders to blackhorn powder indirectly, if I hadn't learned about it and the ease of using it and the performance of using it I would have never picked up a muzzleloader, for me personally shooting black powder or tablets shooting once or twice swabbing in between and then breaking the whole gun down to clean ,,I'm sorry I would have no part of that, no offense to you that shoot it,, there's a lot of information on black horn powder read and then keep reading,,and I know you can talk to a lot of people here that have shot a lot more pounds of blackhorn than me, good luck, learn to shoot the recoil of your rifle when you get it also, and be patient with that aspect,I've seen a lot of people that had an accurate muzzleloader inline CVA traditions etc,, they quite honestly just couldn't shoot the gun,, there's a lot I could say about the different recoil signatures of different muzzleloaders, I'll just say this today ,the recoil signature of the light weight in line 50 cal as experienced by the shooter is longer than the sharp crisp recoil of a centerfire rifle, instead of recoil straight back in a sharp line they jump and come back, stay tight shoulder and follow through,,,, maybe that's a topic for another time but for me being a little man how I manage recoil is very important but I've seen a lot of big man that couldn't handle it too.
