The 357Sig lags, esp. if the bullet weight goes up past 125gr.
+1. As I've written before, the .357SIG is a ballistic one-trick pony. It's designed to emulate the ballistics of a .357Mag, but only using 100gr-125gr bullets from a 3"-4" barrel. It does this very well, but its lack of case capacity makes it incapable of handling 158gr-180gr bullets and/or large powder loads that take full advantage of 6"-20" barrels. Consequently, its performance against medium to large game comes up short compared to .357Mag.
