Corbon ammo is overpriced possibly dangerously overpressure crap. I would never buy it again or shoot it out of any of my guns. I bought two boxes of their 110 gr .38spl+p stuff for my 642. while I was testing it at the range, I noticed that the bullets were severly backing out of the cases as I fired it and checked the remaining rounds in the cylinder. I called corbon and asked and was told that was normal even though the ammo was supposedly designed for the light weight snubby revolver. Just what I need ammo that could malfunction and tie up my revolver in a self defense situation.
Federal PD 110 does not do that, and when I tested the federal 110 gr NON +P against the corbon I got the same penetration with less flash , recoil was similar, and guess what? the federals did not back out of the cases, properly crimped apparently.
