Methinks you have a mag issue, not an ammo issue...[/QUOT

It happens with all 5 mags. I'm going to buy some Stingers & see what happens. Also just load 9 rounds

Do you store your mags fully loaded? That might soften the springs a bit and not press so hard on the bolt when the 10th round is loaded?

Most .22LR that is not labelled Standard Velocity or "sub sonic" or "quiet" will likely be over 1200 fps at the muzzle.

X2 exactly. Gopher shells.

best out there is the CCI Velocitor if you're looking for killing power. at 100 yards it maintains 104ftlbs whereas everything else is 80ftlbs or lower.

if you want pure velocity, then the CCI Stingers, followed by the Velocitors.
