The math:
.357 mag, 158 grain SP, 1825fps (really pushing pressures...) 18 inch carbine:
(158/7000)(1825 squared)/64.32= 1169 ft lb
30/30 150 grain SP 2190fps, 18 inch carbine:
(150/7000)(2190 squared)/64.32= 1598 ft lb
430 ft lbs is 27% more energy in the 30/30....
If it really boils down to preference, be my guest, but don’t think the 357 carbine is in the same league as a true rifle cartridge.
Yup
