At this years Florida Open was I using my Open class SVI IMM in 9 Major. I decided to shoot Open after reading about AA .355 Super so I ordered 1000 rounds and had it shipped to friend of mine in Phoenix . When I tried the ammo was I impressed to say the least. The chrono showed a factor of 168 that is major with room to spare. What impresses me most is that it is very consistent and the accuracy is good to say the least at least in my gun. I know for sure that I will use Atlanta Arms ammo again, they arent cheap but quality seldom is.
