Take out the buffer and give it a try. Or try some factory ammo and see if it will lock. Sometimes going with a reduced gas bushing and a recoil bushing will cause just what you have happening + the reloads that may be a bit underpowered.
I just went with a 1911 buffer at the receiver and have not had any problems with any ammo I have shot and my bolt will lock back on the last round. It still flings the brass but I would rather have to go into the next area code to pick it up then have a rifle that might not be reliable when I might need it the most.
