I have not had any trouble at all with the Large or Small rifle but I have only fired a few hundred of each.
Now on the Small pistol my Glock 34 had a few that would not fire the first time but once I tried a second time they fired. I blame it on my lighter spring and they may also have a harder cup than the Rem primers I have been using.
I will say they performed well enough I bought more of the SR and LR while they were on sale this week.
I now have enough on hand to make it thru Hillary's first term.
