I just won an S&W M49 on GB. By the serial number, it was produced in '81, so it's probably regulated for 158-grain bullets and should work with 148-grain wadcutters. Right now the only powder I have is BE-86. Has anyone come up with a load that approximates factory wadcutter velocities with this powder? Since it's close to Unique in burning speed I can use that as a starting point, but I was hoping someone has already skinned this cat.
