In hunting rifles, heavy for calibre, eg 180gr .308 loads do exceptionally well in terms of penetration and performance compared to lighter loadings.But in handguns, Looking at test results for 9mm 124gr vs 147gr, i dont see much of a difference in penetration for common duty loads, so would the only advantage be the lower percieved recoil? Or do the 147gr offerings bring something else to the party?
