I think people have been conditioned to have high expectations when it comes to accuracy. It's everywhere in the gun world, not just here in the traditional muzzle loading community. I've seen it in all aspects. People expect bullets and ball in the same hole kinda accuracy then complain and believe their rifle is trash if they don't get it. They will print a 2-4" group and start wailing, lol. When in the real world I have never owned or shot a rifle that was not at least minute of deer or man accurate. I have no idea where people get these bench rest standards but its laughable to me. If you have a rock chucker that can hit an 8" plate at 100 yards you are gonna eat tonight. Now if you are competing then all that other stuff comes into play, and is not the point I'm trying to make.
Amen to that. It depends what you do, do you need the accuracy, and are you willing to put in the work. I think the answer for most is no and no. Minute of pie plate accuracy at 50 yards is great for a deer in thick pa woods, or just for some plinking fun, but not so much for competitive shooting.
I think where I might disagree with you is I think most rifles, especially muzzleloaders are more accurate than the shooter. How many of us shoot standing unsupported? Can't blame the rifle for that. How many of us use open sights? The margin for error is so much higher than with optics, again not the barrel or bullet's fault.
Even with modern firearms most aren't getting that accuracy with factory ammo. They're just getting help from optics and a sled or sandbags that get them a 3"group at 100 yards - i.e. it's the Indian, not the arrow.
I also think our muzzleloaders are capable of a lot more if we took the time to figure out what they like and fed them better, but to even notice what better is we have to take our own inconsistency out of the equation. But almost nobody is willing to put in that much work. How many of us weigh powder - the heresy! How many weigh their round balls and throw the extremes back into the scrap lead pile? There's lots of talk about lubes, but how many try 45/55 vs 50/50 vs 55/45 crisco/beeswax (or whatever their homebrew is) and track the results and temperature that day. How many have tried more than 2 types of patch material? How many keep a notebook and measure groups, and record weather , components, and weights, and consistently tweak 1 variable at a time?
I have a [redacted] that shoots cloverleafs at 200 yards. It doesn't do that with factory [redacted].
It requires a hand load with +/- .5gr projectile and trickled load to +/- .1 gr and seating depth that's tuned to the rifle, and consistently trimmed, annealed, and weighed [redacted]. I have to account for temperature of the barrel and shoot slow enough to keep it consistent. I went through an entire spiral bound notebook and a couple hours/week at the range for probably 6 months, constantly making little tweaks to get it there, and went through several different combinations of components along the way. That same [redacted] shoots a 5-6" group with factory [redacted] at the same distance. And if I shoot standing unsupported with iron sights - I'm happy if I can get it on paper at 200 and all that tuning is a complete waste. It took a long time to come around to it, but, back to your point, why fuss if you don't need it because it's not free and unrealistic to think it is.
For me, the pursuit of accuracy is part of the hobby. It gives me a reason to go to the range and waste lead every week to try the little lube change I made, or to try the new patch material. Is it needed - absolutely not. Does it make my rifle trash if I can't make the holes touch - nope.
