Not sure how old the ammo is I just bought it this morning, but it is possible it had been at the store for some time. Is there a date on the box so I can see when it was manufactured? I am using an A2 stock so I have a rifle buffer. This did not occur with the other hornady ammo I have just with the vmax, and it happened every time on the last round of the mag unless I rapidly fired off 3 or more in succession. The ammo put off enough pressure to allow the bolt catch to lock the bolt but it would leave the bolt about a half inch short of a full cycle preventing it from stripping off the first round of a fresh mag.
Thanks for the link, I will be sure to direct my dealer to that page of their website.
