Thanks. I thought it might be a caliber I was unfamiliar with as I hadn't seen it put that way before.
I always thought the .38 Super could be made to significantly out perform the standard 9mmP. Has that changed? Same for the 9x23, It too was touted as the new Wonder 9 but it seemed to die quickly as well.
I can only push my 9mm Win Mag (9x29) to around 1,500 with a 126gr projectile.
