A while back a group at our range was shooting 12" dingers at 200-500 yards and I brought my Sharps as it was looking neglected in the safe. I had shot these before with a scoped AR (too easy) and figured the Sharps would be a challenge as well as entertainment value for the other shooters. I had not fired the Sharps at longer range steel since I last shot BPCR silhouette back in the 90's. I only had hunting loads with the 330 Gould and Lyman 457193 loaded over 29gr and 27gr of 5744 respectively. Both of those loads shoot 2 moa or a bit better but I never shot them past 100 on paper. I shot the 457193 loads and did very well up to 300 yards and hits were easy once I got the sights dialed. At 500 yards it fell apart and hits were few. One of the shooters told me about the Quigley match and after looking it up a friend and myself had decided to attend. The 400 grain boolits are obviously not going to work for the Quigley with targets from 350-805 yards. I have not fired any 500+ boolits in the Sharps since the 90's and those were loaded with BP. The proper grades of BP seem to be unobtainable presently and it looks like I am going to have to use smokeless for my 525 grain loads. Looks like 25-27 grains of 5744 (have a bunch of it) will get me in the 1200-1350fps range. Hope I can find adequate accuracy and low enough SD's so vertical stringing is not problematic. The chrono will tell story on SD's.
