“They are nice little guns. I have a 2nd change made in 1907 and I shoot it regularly with a case full of Swiss 2F and a 115 gr. bullet.
I get the best accuracy from that load. Lots of fun.” smithra 66
“Heat treatment cylinders around serial number 80,000 in the 32-20 k frame. Post 1921 manufacture date,, no more round butts. Great job bringing that one home, and sharing.” 4K2022
Well, both of you hit me squarely! My old M&P is in the 75XXX SN range. I’ve always been a little hesitant to get very enthusiastic with my reloads, but BP loads might be a possibility. Of course like any self respecting 32-20 loader, I have a good old Ideal 3118 mould for 115 gr bullets and just happen to have a can or two of Schuetzen Cartridge grade BP. I may have to whomp up a small batch of BP 32-20 cartridges to see how they do… I’m not going to start out by using up these hard found new cases, but I do have a small odd lot of once fired cases I could clean thoroughly and devote to such an “experiment”.
