Much like several other posters, I aim dead-on out to 50 yards. I use dove-tailed primitive sights, out-of-the-box, and adjusted the rear sight horizontal with a block of soft pine & a hammer. That was years ago! Great for Novelty & Rondy targets! Rifle cuts a playing card in half if I do my part! When I shoot paper, it's either at 50 or 100 yards. At 50 my rifle shoots pretty flat and at 100 I compensate by covering the entire bull with a 12:00 hold :shocked2: and the balls fall into the deep part of the black.
From there I've learned where to hold to shoot 370 grain T/C Maxi-Balls out of my 48-twist rifle as well: at 50 yards I use the 12:00 hold and the conicals fall into the ten-X ring offhand. At longer distances it's a hold over the bull since I have NO vertical adjustment. I'm fortunate since the horizontal remains the same for the Maxi's as well, with card-cutting and 2x4 chopping accuracy up close :grin: .
Shooting the Winchester/NRA Qualification Matches with my Club has taught me and the rest of the folks that do the Match COF a lot, since it's a 52-shot COF :shocked2:. You really get to know where to hold and when to spit-patch if the fouling builds-up a little too much :wink: .
I started the sight adjustment for the rifle at 25 yards, then backed-up to 50, working off a bench.
Since I do more competition than hunting, I always pump the first round into the berm to foul the rifle, unless it's a Novelty Shoot where I shoot one of the larger targets first to foul the gun with a hit instead of just pumping it into the ground.
Hope this helps explain why I'm a little A-R :haha: .
Good luck with what ever technique/sights you use :thumbsup: .
