  1. I've had a torn bicep for 2 years and it has not affected my shooting. Overtime it has, to some extent, slowly healing itself.
  2. You can shoot 9 x 23 in a Super barrel but I don't recommend it. Its obsolete and brass is difficult or impossible to find. I shot it for years and have a 95 gr. steel load if interested.
  3. I've been a Super Senior for 15 years (You used to only need to be 60). I try to hit the gym 3 days a week and alternate between the Concept 2 rowing machine and an Espresso bike. I do 5000 meters on the rowing machine and somewhere between 5 and 8 miles on the bike. I don't do much weight training but do dead lifts, pull downs, and chest press on a machine to hit the muscles not worked with the rower. Back in the day, I kept a tennis ball in the car to squeeze at traffic lights.
  4. I running the same bullet with 3.8 grains Titegroup @ 1.12 in a GMR-13 and getting good accuracy and no leading in the comp.
  5. My JP GMR-13 has never had a factory round shot through it. 9000 rounds with my reloads and no problem.
  6. I would suggest trigger control. Do some dry fire and concentrate on any sight movement.
  7. When I was a Pin shooter, the pin had to be knocked completely off of the table. All of the good shooters were using .45 pistols. I was running a little over 200 power factor.
  8. I my experience, almost every time I give it to the RO.
  9. I clean about every 500 rounds. Running Titegroup, the gun gets very dirty. Several mentions above about oiling. This applies to the bolt. I run wet. @ 5000 rounds I replaced the firing pin but the old one looked good and I kept it for a spare. Also replaced the extractor but it also looked good. Recently replaced the "O-Rings" in the buffer. They were shot.
  10. Check page 5 for J-P Rifles suggestion. https://www.jprifles.com/document_pdfs/JPSM_729.pdf I followed this for my original .223 barrel and got 10,500 rounds out of it before groups seemed to open up. Just got a new J-P barrel and am following the same procedure.
  11. I dry tumble and use One Shot lube and leave it on. I run 2 different TF = 10 mags and 3 shorter mags with + 5 Dawson extensions.
  12. I'm running Precision Delta 124 JHP @ 1.120" in Glock mags with no problems.
  13. I've been shooting local matches for 3 years with a PCC. Almost all starts have been with butt stock on belt, a few low ready and occasionally, if pistols start "Hands on Xs", PCC starts muzzle on X. That's what I would practice.
  14. I have seen competitors using lasers on rare occasions and considering getting one but decided improving my shooting would pay much better results.
