Thanks to Gun-Geezer for a copy of his load spreadsheet.
I ordered cast bullets from Montana Bullet Works. 200 grain RCBS style with GC’s and blue lube. One hundred sized to .348 and one hundred sized to .349. The bullets were crimped firmly with.a Lee crimp die. I used 27.5 grains H4198 & WLRM primers. I shot a 5 shot group with each at 20 yards. The groups were pretty much identical. The bore was clean - each shot .6” group. Which is about what I could do with those sights. I did take off the hated buckhorn sights and mounted a Lyman Steel aperture sight.
These were from a “new to me” Browning 71, which I got here on the 24.
Next I’ll shoot groups at 50 meters and I’ll measure velocity.
