Cheshire_Cat Posted January 3, 2016 Share Posted January 3, 2016 I recently purchased a Dillon 550b press and began reloading 9mm (5.3 gr WSF, CCI small pistol primer, Bayou Bullets 115 gr, mixed brass). My Gen 4 Glock 34 will not easily manually extract the cartridge. I first noticed this when having a failure to fire and did the tap rack assess...it would not rack. I have to pull really hard on the slide for it to extract the reloaded cartridge. It does not have any issues manually extracting factory ammunition. My Glock 34 has a steel guide rod and 13 lb recoil spring, with the Taran Tactical spring kit. My Gen 3 Glock 19, which has stock parts, has no issues manually extracting the reloaded cartridge. I did notice there is a slash/gouge in the bullet after manually extracting the cartridge. This occurs with both the G19 and G34, although it is deeper with the G34. It probably shows up because it is a coated bullet. Not sure if this has anything to do with the problem or not. The extractor on the G34 does not appear to be broken. In fact, I put the G19 extractor into the G34 and it still had the same problem. Any ideas as to what could be the issue? I think my lightened striker spring may not be a good combo with the CCI primers, so if/when I get a light strike after 20 or so rounds it sure is a pain to have to stop shooting and pull super hard on the slide to get the cartridge to eject. 2 of the times the casing actually separated from the bullet I had to pull so hard...

blairmckenzie1 Posted January 3, 2016 Share Posted January 3, 2016 What is your overall length? Link to comment Share on other sites More sharing options...
Dr Mitch Posted January 3, 2016 Share Posted January 3, 2016 (edited) Too long OAL, barrel leade may be too short. Bullet profile has a lot to do with this issue, Edited January 3, 2016 by Dr Mitch Link to comment Share on other sites More sharing options...
Cheshire_Cat Posted January 3, 2016 Author Share Posted January 3, 2016 I just measured a batch of about 20 and the OAL was about 1.138 (some give or take .002...with a couple .004 to .006 off) Link to comment Share on other sites More sharing options...
Southpaw Posted January 3, 2016 Share Posted January 3, 2016 Have you done the plunk test with these rounds in your G34 barrel? http://www.shootingtimes.com/reloading/reloading-tips-the-plunk-test/ Link to comment Share on other sites More sharing options...
RippinSVT Posted January 3, 2016 Share Posted January 3, 2016 Yup, loaded too long. Bullets are getting stuck in the rifling. Back off a .010 or so and retry. You should be able to slam the round home and then gently pull the slide back and have it extract, Link to comment Share on other sites More sharing options...
Cheshire_Cat Posted January 4, 2016 Author Share Posted January 4, 2016 I was unaware of the plunk test. Thank you for the link. The rounds fail the plunk test in the G34 barrel and pass in the G19 barrel, so I will shoot the couple hundred I already loaded through the G19. I will decrease the OAL .010 and see if those pass the test. Link to comment Share on other sites More sharing options...
dauntedfuture Posted January 5, 2016 Share Posted January 5, 2016 OAL is too long or your brass is not sized enough or your crimp is out of whack. Link to comment Share on other sites More sharing options...
wyliearms Posted January 28, 2016 Share Posted January 28, 2016 I had this happen to a LoneWolf barrel. Had to keep going down, especially on lead bullets. Link to comment Share on other sites More sharing options...
