FWIW I went to the range this afternoon for a while. The standout ammo, for accuracy so far, is the federal 115 FMJ
Tried 4 different carry type loads
The Underwood 90 gr defenders were so-so for accuracy
Hornady critical pitical 115 gr shot like doggy-do, or a shotgun
Sig 124 gr V-Crpwn was the obvious winner for accuracy amongst carry loads. Almost as good as the federal FMJ stuff
Federal 124 gr Punch ammo put only 3 of 12 on paper.
Was shooting at notebook sheets with a 2.5" shoot-n-c. Had one really good target with the FMJ. 8 in the shoot-n-c with 4 close to it. I'm a bit inconsistent with it, though. Had several groups that wandered low and left like everybody has seen. I usually cure this with more finger on the trigger. And that helped some today, but I'm gonna have to figure out the grip.
Mine shoots everything well from 115 grain FMJ to hollow point front 124 to 147 as well as hard cast
