    Cartridges are bending?

    Hey guys new here to the site. So I recently got 500 rnds of frontier 55 grn 5.56 . First Time with this ammo . Was shooting Winchester 55grn . Out of 70 rnds I had 5 rnds that got bent by bolt, like they didnít camber right. No issues with my gun and the Winchester ammo ever before. Just clean the gun a day before shooting. Just trying to figure out if itís a bolt,gas or ammo issue. Thanks

    Tell us about your gun.

Many people look at 9/11 and wonder how we can stop an enemy like that. I look at FL93 and wonder, "How can we lose?". -- FromMyColdDeadHand

    Bullet is definitely slamming into something. Could be a combo of bad ammo and a flaw in the upper assembly... or just bad ammo period. What the ejection like... snappy like the ammo is too hot?

    Try a new bolt.

    Last time I saw that was from a bent extractor. Although it wasnt that bad. Looks like the cases are really soft, or they are getting slammed super hard.
