I just got two new Uberti 1873 lever actions rifles in .357 and .45 Colt. I was wondering what load works best in your rifles. So I can try them in mine. I'm currenting using 8 grs of Unique and a 250 gr swc in the 45 colt and 5.5 grs of Unique and a 158 gr Lswc in the 357 mag. So far so good with both but worried the .45 colt could be a little hot. Any suggestions.
