I have two Uberti revolvers, the 1851 and 1861 models, both converted by me to use the 38 S&W cartridge. Modern steel cylinders and recoil plates were used. The bores are .375 inch and I use a 127 to 130 grain hollow base lead bullets around 359 diameter with 2.7 grains of Unique. These are not target pistols but have a certain amount of accuracy at
close ranges. Empty cases eject without any problems and without sight of high pressure and they are fun to shootAttachment 84201Attachment 84202
