I've been extremely happy with a commercial 200 gr. LRN out of my 1911s. So much that I thought I'd give them a try in my Glock 30. That was not a good decision. Problems from the start with feeding, extraction, and so on. As has been discussed here a number of times, Glocks don't get along with SWC design bullets, and I started to think that perhaps the LRN design I've been using was too much like a SWC to function though my Glock. There is a definite "shoulder" where the bearing surface transitions to the round nose (ogive). At the shoulder, the bullet diameter steps down from .452 to .405 diameter. Do any of you lead loaders, have experience with such a lead bullet design in Glocks or thoughts on what might be going on? FWIW, the loads were fairly light 5.1 gr of 231 with an OAL of 1.244. Obviously, the thing for me is just not to use this design of bullet in the Glock, but I am just curious about some expert thoughts on the possible issue here (and it was time for a post of some kind....). Yes, I am up on the lead vs. Glocks debate, so we don't need to go there... Wanna kill these ads? We can help!
