Both Keith with his .75 and my .69 used to use 30gr. 2F for the bunny charge. At 25 yards, they shot almost on the sights, and would of course punch an oblong single hole for groups of 4 or 5 at that range. They were so slow, but accurate enough for the normal close shots and you could distinctly hear the ball crunching on through. What fun!
Keep working on your loads, Razz, both ball size and/or patch size - you'll come up with a combination you can live with. I do strongly suggest you shoot at 50 yards or farther, though. 75 would be a good comprimize between 50 and 100. Generally speaking, any load that shoots well at 75 to 100 yards, shoots well at all ranges. 50 yard groups are an excellent indicator for load potential. 25 yards is too close for extablishing hunting loads, in my honest opinion. I do use 25 yards for sight-in, though, then check at longer ranges to establish the drop. With hunting loads in the 1,800 fps range, a 25 yard zero generally gives a 50 yard zero as well - to about 1" to 1 1/2" high at 50 yards. This depends on sight height, of course, but in general terms, is close enough for hunting without drop worries to 100yards for a centre hold on a deer. The most drop below the line of sight you will see is perhaps 3", still well within a deer's vitals. Sighting for 1" high at 25 yards should give centre holds to about 115yards, maybe more depending on sight height.
