I loaded 100 rounds to the following specs: 200gr XTP 9.0gr 800X OAL 1.253 CCI300 primers Starline brass - new 1/2 turn on Lee FCD Lee carbide dies with FCD and Lee Bulge Buster I had failure to feed issues with my G20 setup as follows: Gen 3 Glock 20 KKM standard length barrel 20# Wolff recoil spring +10% mag spring Rounds would hang up by 3 points,,,the bolt face, the feed ramp and the top of the chamber (possibly called a 3 point ???) Another shooter with me had a 100% stock gen3 G20 -- no mods whatsoever. With a loaded mag, the slide pulled back and let go to chanber a round......the round would hang up just like above. The round would be hung up at the top of the chamber, the feed ramp and the bolt face. This failrure occurred several times....only when you forcefully would snap and jerk the pistol would the round chamber. During firing with the stock G20 the same hangup would occur. When home I measured some DT 135's and some 180's. The only difference I could see was the DT rounds OAL was 1.243 while my OAL was 1.253 which is well within any spec I've ever seen. I'm beside myself. I didn't think reloading was that sensitive to minor variations....I mean a stock glock will not eat my reloads. I just do not understand what I could possibly be doing wrong.
