[QUOTE="del2les, post: 2496393, member: 9299"] I have seen this with minimum dimension target chambers with minimum head space that once dirty via a few shots, began to have very similar issues. Also, we have seen a few experience this with handloaded ammo that was not small base resized. I have a very tight minimum AR 223 Target chamber/barrel that must have all reloaded ammo small base resized and shoulder bumped to feed properly, and it has experienced similar issues with certain brands of factory target ammo. When the bolt is dropped on a single, it has sufficient forward force to basically bump-size the shoulder via the chamber, but when using a fully loaded mag, the increased drag reduces the forward bolt thrust until a slightly dirty chamber prevents lockup. The round not feeding completely from the mag is a separate issue, but it can slow down the forward thrust. EDIT: One thing I forgot was we used a dry silicone spray on a clean cloth to rub the rounds prior to loading, and this gave improved feeding and clambering for a while. But this is not a longer term solution for a minimum chamber and tight headspace. Polishing the inside of the mag lips can also help. [/QUOTE]
