Ya, I would pull em and reload them myself... No way I would trust the powder on those if he managed to screw up the OAL that way.
I have never trusted reloads in the 40/10mm due to the fact they are loaded with the same powders (type), and same dies for both, just change the depth.... If he screwed up the OAL then did he remember to change the powder to match the 40, or 10mm?
You may have the new 40 cal mags, I hear they work great but the gun will only handle a few rounds.......
Never shoot reloads that they do not have all there info printed on the boxes.
GOt to ask, what is your life worth? saving a few $ on some unknown reloads.
Learn to reload or get the big brands that will stand behind them.
