....I stand corrected sir. just looked at it in my extra parts bin.duh!

If I took a swag I'd say the double action hammer sear is slipping off the trigger and not engaging the trigger when pulling the trigger in double action mode....just a guess. There is a small leaf spring that activates the double action sear. If that breaks or is damaged it will not engage the sear/trigger.

I have finally gotten around to do some in depth checking of my sticking rounds. It appears that the ogive of the 115gr. LRN is rounder than that of a let's say a 147gr. FMJ round and consequently contacts the end of the chamber. It was mentioned earlier that LW barrels are suspected of possibly being a little tight or short in the chamber area. I contacted LW about my issue and they assured me that their barrels are cut to factory specs, however if I were to send them the barrel, three of my rounds and $35 they would recut my barrel to fit. I didn't quite like this idea. I have no other issues with the barrel as it seems to digest FMJ's ok. I got ahold of another drop in 9mm aftermarket barrel made by KKM to use as a comparison. The KKM barrel had no problem with digesting any of the LRN or any FMJ's. All of my LRN dropped fully into the KKM barrel chamber to the proper depth and easily fell out when the barrel was inverted. ....I would like to thank everyone who offered their advice.

First of all thanks to all of you who responded to my problem. I had to close shop for a few days so I won't be able to check anything until Jan.7th. After reading your posts however, I am noticing that the Missouri 115 LRN 9mm Parabellum bullet I am using has a more rounder head than some of the others so it just might be engaging the rifling and shortening the OAL cautiously might be my answer. I also understand about being mindful of increased case pressure and backing down the powder. I have always used TG or Clays and I am reading more about N320. . I am just interested in knocking down steel so if anyone has a better setup for 9mm I know how to listen. "..............Thanks for all of the advice so far and will keep you posted soon.

Hello, I have been reading the forum for a long time but never had a problem reloading with my RL550b until recently starting to reload 9mm. I have a G17 with a lone wolf barrel so I can shoot lead. I am only used to reloading MGJHP in my G35 so 9mm is new to me. I am using 4.0 grains of TG behind a 115 grn. LRN. My load data lists an OAL of 1.100. Compared to factory ammo tha is a lot shorter. I have several issues however when attempting to extract and clear the weapon with a loaded round in the chamber . The round is very hard to extract and invariably I end up separating the round in the chamber with powder spilled in the chamber area and having to clear the bullet head from the barrel.. I am pretty sure it not a seating or crimping problem but not positive. With an OAL of 1.100 could it still be to long and the bullet head is engaging the rifling. I have examined the stuck bullet heads and cannot see any conspicuous marks. At 1.100 I do notice with the 115grn. LRN there isn't much distance left between the case neck and the bullet head lube ring. This forum is a wonderful tool and I hope there is a solution or did I error on purchasing 4000 bullet heads.
