I bet you have a bulged case issue. Once the brass is shot through the LWD barrel the bulge will not be an issue. Remove the barrel. Drop your reloads into the chamber and use it as a go, no-go. The round should sit just under the barrel hood. If so, it is good to go. If the load flushes up with the barrel hood you may or may not have a feed issue. If it is above the hood it is a problem for sure.
Watch your OAL. Slightly shorter is better
I appreciate the information. To be honest I haven't used the Glock barrel as of yet on either my Model 21 or Model 35. My concentration and learn ing curve has been with the 21.
The Lee bulge kit arrived yesterday and I used it to resize 50 cases. All cases are federal and the case thickness averages .011. I'm now loading RNL bullets with an OD of .451 I am taper crimping the necks and it measures .468. My OAL is 1.265 which is .010 shorter than the maximum OAL shown in my Lyman reloading book.
I also have reloaded 10 of the Federal cases with the SWC as an experiment just to see if the feeding problem still exists now that the cases are properly sized and taper crimped.
Interestingly enough when using the LW barrel for my go, no-go gauge the rounds drop in freely with an audible clunk but they honestly don't sit just under the barrel hood as you suggest. Most are even with it and a few a hair high. In the factory Glock barrel all rounds fit below the hood and rattle around like a glass eye in a tea cup. I had read that the Glock chamber is over size and obviously it's true.
I will be at the range tomorrow and will fire the rounds and am particularly interested in seeing if the SWC's feed properly and making sure that all rounds lock up which was amajor problem previously. I immagine that having used the Lee bulge removeal kit and with the proper taper crimp all rounds should chamber and the slide should lock.
