I still have a decent supply of the last run of Centurion stuff to last a while. Will still be laying in some of the new offering anyways. Not sure what the real world numbers are on the new ammo. Published numbers show it's de-tuned a bit from last time.
The Centurion stuff shot great in my 592M. Not as great in my 591M. Luckily, the 592M is my beater/shooter more so than the 591M.
