What these guys are saying is that they are tryingto fill in some of the things that may not be considered by a first time muzzleloader. Step back and take the words as offered advice to prevent someone from getting blind sided
I have been shooting sine I was 8 and I'm almost 41 now, I've spent 17 years in the military and shoot to hunt as well as in competition, so I'm not new to firearms, but I'm new to the traditional shooting forum.
Muzzleloaders do take more effort in set-up and familiarization. My Traditions was previously owned but I bought it with no load data. The woods I hunt in are thick, like machette thick. 50 yards would be a long shot for me to take in these woods. I spent some time at the range with an adjustible powder measure finding the load that grouped best and hit to POA at 50 yards. getting a hang fire or anticipating your shot and flinching, or not providing proper follow through on these guns can have a larger effect on shot placement than with modern centerfire guns. My front sight also had to be drifted. And I f I wasn't shooting to Point of Aim I may have had to file the front sight.
Once you find the right load, then you can be assured that the rifle is capable and go to the woods with confidence.
My chosen load: (the two off to the left were when I found my front sight had been knocked loose. I had to drift it and stake it at the range. The round that is slightly above the ragged hole is from me not following through properly on my shot and giving the rifle slight movement before it truely fired.)
I find nothing wrong with a desire to extend your season. I also wanted to extend mine, as well as broaden my shooting experience into a field of shooting I hadn't previously explored in any depth.
Try not to take any of the comments personal, and just understand that this branch of shooting has some dark litte secrets that nobody wants to see you or your game suffer for.
