Can you explain what you mean by fine sight? I'd sure like to be able to shoot those groups with my P53. Really great shooting! Do you like the trashcans more than Minie or Pritchett style bullets for your gun?
A picture is probably the best tjiann,
to explain what I mean by a fine sight - see my image below the text. I do like the trashcan target minies, as out to fifty metres I find they are very accurate with light loads. My aim here, (no pun intended, right?) is to enjoy the '53, yet save on powder consumption. Real black powder here in Australia is expensive. Another mold I like too in the '53, saving on lead and powder, is the Lyman 575494 - again image below. The Lyman 575213, 510 grains, is a good mold too, but the melt really disappears when casting! More powder required for these too.
When I first started shooting this rifled musket, I was lubing the minies by dipping them into the melted beeswax lard mix (70/30) with needle nose pliers; I loaded them as is, simply using the muzzle to remove the excess lube. This proved to be horrible for accuracy at 25 metres onwards. On the advice of one of our stalwarts here, he firmly told me I had a good lube, but too much of it, the excess preventing the skirt of the minie from being bumped up into the rifling. So, I made my little funnel device to remove the excess lube, and hey presto, the little darlings actually grouped! Then, I was watching the European Nationals on YouTube, and noticed that nearly all the military competitors were using a filling of corn meal over their powder, before seating the minie. I did this, and my groups shrunk again. Mind, all these targets that I present are shot sitting down at a bench with the rifle resting solidly on a front rest, supported by a small bag at the rear, taking care to follow through at the shot.
There are others on the 'net who write they get consistent two inch groups out of their 53s at 100 metres. I'm sure not there yet, and probably never will be, but I'm more than happy with my current results. I've got a leave pass from OC Home Command again tomorrow, so I'm going to attempt another run at 100 metres with the trashcans, and if time, a group at 50 metres with some .562 round balls. We'll see ...
