I don't blame ya. I did the same thing. The purpose of this 9mm on steroids (357 sig) was supposely to match 125gr 357mag speeds. But I don't see the simularitys. I have never reached 1600fps velocities a 357mag can. I know alot of factory ammo is more like 1450fps. Fast I can get with Unique powder is almost 1300fps. But my gun is a subcompact. Also supposed to feed very smooth. The problem for a reloader is there is not enough neck to hold the bullet.
