A quick search of the archives didn't turn up the average bore diameters of the Miroku 92 357 and 44 mags. I'd like to pair up a handgun and a light rifle/carbine and would like to be able to interchange rounds between the two with "acceptable" if not optimal accuracy. So relative bore diameters between the handgun and the rifle become important. I think it might be hard to pair a S&W 29 with a Marlin 1894 in 44 mag, for instance. So, anybody help me out with those bore diameters and what might your thoughts be on my project? Thanks all, IrishFritz. P.S. I should have added I shoot lead bullets only.
