  1. I used the Odin AR part and drilled and tapped the original JP mag release.
  2. I switched to the Techwell and it works fine. Best improvement to the GMR-13 was an extended mag release.
  3. I have been shooting USPSA for many years in Open and Limited pistol class. The biggest change for me shooting PCC was thats its scored minor. You get 3 points for a C instead of 4 points. Concentrate on trying to shoot all "A" s. I am not shooting on the move nearly as much as I did with a pistol. I'm a B shooter is all classes.
  4. Punch and hammer works and small engraver tool works as well. Switch to JHP and the problem goes away.
  5. I'm running a JP GMR-13 with their trigger. Without any attempt to lighten the pull, its now about 2-1/4#. I run a Geissele 2 stage in my "PRS" type AR and like it for that purpose. Tried a 2 stage in the same gun when shooting 3 Gun and went back to JP.
  6. I ordered the spring pac and use one of the lighter springs in my GMR-13.
  7. I have a JP GMR-13. Over 8000 rounds and several matches. I've had two malfunctions, 1 primer didn't go bang and somehow a .380 case got through my ammo check.
  8. If doing thousands, Giraud. I use one machine with two different cutters for .223 and.308. It's so quick and easy that I run all of my .233 brass through it whether they need trim or not. Way faster then measuring length.
  9. I used my Open gun for steel as well as USPSA for many years. I used a 95 gr JSP bullet running 117 PF as a steel load.
  10. Using a TF +10 with a Glock 33 mag, I've never had to reload on a normal USPSA stage. The last match I shot was a Monster match and one stage was 62 rounds but no issue reloading during movement. My buddy ws using a MBX 57 round mag which eliminated all reloads except for the stage previously mentioned.
  11. I have used Delrin in the past to make auto racing suspension bushings. No failures. Trying to save 1.7 Oz when a loaded mag is pushing 1# seems like a waste.
  12. That mirrors my experience. GMR-13 with 14.5" barrel. 3.6 gr Titegroup, Precision Delta 124 JHP is a good all around load. I shoot USPSA as well as KD Steel and occasionally Steel Challenge. Previously tried 115 and 147 bullets.
  13. Ruger factory shooters James McGinty and Dave Olhasso just came in 1st and 2nd in PCC out of 124 PCC shooters at the Blue Mountain Classic Steel match.
