Last year, Hornady released its Critical Defense® ammunition. Originally beginning with .380 ACP (90 gr.) (for all of the new mouse guns that have been released in the last year), .38 Special/ +P (both 110 gr.), and 9mm (115 gr.).
Recently they added .357 Magnum (125 gr.), .40 S&W (165 gr.) and .45 ACP (185 gr.). I’d be interested to know why Hornady went with a 165 gr. .40 S&W rather than a 155 or 140. I’d also be interested to know why they chose a 185 gr. .45. Does anybody know?
