  1. I would take the time to tune to my loads for $1,000 even, if your interested.  I am solid buyer ( and Seller ) on this forum.

  2. FYI, my issue is not related to bullet profile, I’ve actually seen where the brass is catching on the edges right off the feedramp, about 3:30-4:00 o’clock area assuming the feedramp is 6:00 to 5:30. That is where I added a bit of relief and polish. I will definitely look you up next time I’m in Rio, I’m planning on shooting the JP match in Feb...
  3. Thanks for posting, I’m surprised no one has jumped on this yet, seems to be an issue, particularly on the Gen2, I just finished mine today, mostly polish with a small amount of relief to the sections just above the feed ramps:
  4. Makes sense, I have a friend who shoots production, he also wants to shoot PCC every so often and wanted to have one load for both, not much luck there, but I’m sure it’s possible if you really work at it. Luckily I shoot Open 9major, so no chance
  5. I'm curious, why so heavy? Most guys I know, myself included are running 115g bullets in the MPX, it seems to do better with more gas
  6. ILWT has a great spare parts kit, otherwise call Sig anyone has anything else to add concerning reduced power recoil springs?!?!?
  7. Anyone heard of this or have anymore details, other than the obvious: " explained the feeding trouble I had experienced earlier in the week and he patiently went over his modifications to the MPX, including rounding of the edges on the magazines and barrel extension. I remarked that I hadn’t had a malfunction yet and that it seemed OK. He wished me luck and left the stage. Of course with these words spoken Murphy just couldn’t resist. Halfway through the stage, I suffered a major malfunction that required complete stripping off the magazine and some beating of the rifle to clear it. I luckily was able to complete the rest of the stage in double the par time with a near the bottom finish. I limped through my last stage of the day gingerly shooting slower than normal in the hopes the malfunction wouldn’t appear again. I had a big decision to make that night. Take Greg’s advice and dremel my nearly $2,000 gun without test firing it first at a major match or hope and pray another catastrophic malfunction doesn’t occur. I decided that no matter what I couldn’t risk more malfunctions and I quickly did the easy rounding of the steel feed lips to the magazine. I pulled the MPX barrel off and saw exactly what Greg had been talking about. For whatever reason, there is more metal on the left side of the MPX barrel extension and it is common to have a malfunction on this side, especially with the hollow point ammunition I use. I followed Greg’s advice and felt where the rounds were catching on the brass lip and began to slowly round the edges off until the rounds feed buttery smooth. I reassembled the gun and hoped for the best the next day." http://exclusive.multibriefs.com/content/duel-in-the-desert-the-2018-uspsa-area-2-championship/recreation-leisure
  8. Anyone else running the 13% reduced recoil springs by ILWT, and at what PF? What benefits, gains did you experience? To the OP: "Tappet and gas plug rings - as needed but no more than 5k (gas plug isn't as important but prob worth doing at the same time)" You "replace" the rings every 5k rounds?
  9. Agreed, mine seems to run best at the 140~145 PF, and yes the 115g bullets seem to be right projectile for this platform.
  10. That's good to know, I have 8lbs of TG as well as a few LB's of Clays, I was concerned that the FAST powders would cause cycling issues,...is your GAS system still factory or have you made modifications? MY MPX runs amazingly well and shoots very soft using factory ammo, just haven't had much luck loading for it. I typically shoot OPEN-9major, so I though I would try HS-6 as its what I have readily available. But again, I will try some fast powders and see... thanks
  11. Hi Eric, so you are having good results with Tite Group in your MPX? I though the gas system would prefer a slow burning powder to cycle better? FYI, my concern is not dirty vs clean, my concern is reliability, thanks
  12. This / I use a baby stroller type cart, with the PCC in a rack, muzzle down
  13. Thank you, it was built by DonF, goes by "donnyglock" on the forums...its 9major
