issue with AR's

[Undergiver]

I have only shot my Armalite once 10rd rapid fire. No Stoppages. Will give another range report when optics are mounted.

Is that the so called Varmint Load bullet? The ones they used to sell at Walmart?

yes the problem is they are not crimpedin the case hard enough so when the gun feeds them it as often as not pushes the bullet back into the case which can cause misfeed or if it does chamber can cause high pressures.
