Recently I had a very similar incident shooting a Remington (R1) 1911, with some .45 ACP catridges I had just loaded. 230gr CMJ's.

First 4 shots went down range and then a misfire. I dropped the magazine out and attempted to extract the unfired round. The slide was very difficult to retract. With some effort I locked the slide back and retrieved the unfired round.

I decided to curtail any further shooting and go check some things.

I rechecked the COL and found it was out of spec'. 1.290" instead of 1.260". I figured that the bullet had engaged the rifling before head spacing correctly on the rim, just enough to prevent the gun from going into battery. The first 4 had gone into battery and fired. The fifth round did not. The difficulty I had pulling back the slide was due to the fact I had to pull the bullet out of the rifling.

I checked the rest of the loads and they were all a bit too long. This was my mistake in that I must have failed to do a final check of the COL after the final settings with the seater/crimp die.

I brought the remaining rounds into spec' and they all fed and fired just fine.
