Real question about sectional density because I’m not that well versed.
Assuming 100% weight retention of both bullets (the 120 7mm & 125 308), other than penetration what effect does the SD have on the killing power?
Given these modern bullets that retain their weight if you're not shooting long range what's the advantage to a higher sectional density? I don't think either would be lacking any penetration at hunting distances.
I'm no expert but if both bullets being compared will both fully expand and give an exit wound then sectional density is of little importance IMO. It however would matter if larger game like moose and bear were in consideration also in a combat situation where barrier penetration may be an advantage.
