I’ve used 147gr HST and 124 gr Gold Dot in 9mm. 38 SPL I almost exclusively carry wadcutters in my snubs.
What advantages would the 356 TSW loads give me over the 9mm loads I currently use? Keep in mind that the extra velocity/energy is going to increase recoil and decrease the number of rounds that can be comfortably fired in a practice session. Plus I imagine it will increase wear on the pistols themselves. How do these new 356 TSW loadings overcome those negatives?
