  1. I hear ya, and I hope its as simple as this.
  2. I agree. However I just came back from the range, rounds with 3.7 gr Clean Shot with 125gr Blue, it was a single shot for the first 4-5 rounds, had to rack bolt to chamber next round. 4.0 gr CS same bullet had usual FTExtract jams. The piston exp chamber is absolutely clean. Now it seems like maybe the gas port is partially clogged?!?!? I have some factory ammo I plan to see how it runs with (Winchester, WWB, and PMC) that I've had stashed away. If it runs ok with these, then it's time to work up a new load. Maybe CS is just too fast a powder? The last hand loads I recall that I ran consistently in it were 124gr Zeros with W231. Oh, and I have a new MPX PCC on the way from Sig, but I need to get this one squared away. TIA
  3. Pic of the crap scraped out.
  4. Yes. I soak the plug and tappet in kerosene for several days, then run them in an u/s cleaner for an hour or two. After taking out of the u/s I make sure rings turn freely, and the chamber in the plug is clear. EDIT: @2011BLDR I think you are probably spot on. I thought I had been cleaning the expansion chamber out enough, but apparently I have not been paying close enough attention to it. Below are a couple of pics of cleaning a plug out, that I believe had been giving me the most issues. When I started, the pick went halfway down the chamber. Adding gas (higher powder charge) to this shortened chamber, would have exacerbated the problem. Correct? Thanks very much!
  5. Why I went back to stock extractor & spring. Will see if that helps. Ejector is tight. They are supposed to be better. There are a couple of good guys involved that are trying to do good. Will see at the next one.
  6. Need some help from the collective. MPX Gen II, upgraded BCG (with fp spring) from Sig (couple of years ago). I've owned this for a few years and have played with it off and on, but decided this season to go full PCC. Just lately it has really gone down hill, and I cannot pin point reason. Current load is 4.0gr Clean Shot with 125gr RN Blue Bullet at 1.100, PF 143-145. Last two matches were DNFs because it FTExtract so bad, there was no point in going on. Each time, it would happen 3 or more times per stage. Each time, I would take same loaded mags, go out back of the house when I got home, and dump the mags with no problems!! When the FTEject happens, the fired case is still in backwards with the next round or two jammed up under it. I can go to the range and blow through 2-300 rounds with no issues. Go to a match, and it chokes on me. No change in my grip, how it's mounted, mags used, etc. Pertinent info: - Mags are GenII as is the MPX. 1x20, 1x30, 1x34, 2x30s with Springer +10 extensions. Springs appear in good shape. All mags have been used numerous times during life fire practice with no issues. - Local match last night it puked on stock 30rnd mag. - I had been running 3.7 gr CS, it was suggested that maybe not enough gas was being generated, so upped to 4.0 at 143-145 PF. 3.7gr CS was 139-140 PF - I have 3 sets of "open" gas plugs and tappets from ILWT, that I rotate when cleaned. - Gas port is still stock. - Piston/tappet is NOT oiled, installed dry. - Deep clean (swap plug/tappet) every 750 rounds or so. - Each deep clean I take a wire and ensue the gas port is clear, and take an old barrel brush to clean out where the piston goes. - Been running with the SSI billet extractor and extra power spring. It was suggested the e/p springs are intended when running suppressed. Swapped back to the stock extractor/spring last night, will see how it runs this weekend. - Match a couple of weekends ago, it DNF on me, I may have had the rotating pin 180 out, causing the pin to hit on the ejector. When I got home from match, pulled it apart to see if anything was wrong (saw marks on round end of pin making me think it may have been 180 out), put it back together, and ran 50 rounds through it with no issues. Yes, I know the dots need to line up. - Ejector is not loose, and does not appear to be damaged. - Recoil springs were replaced with stock weight probably about 2K rounds ago. - It is possible the Clean Shot is too fast, but it is supposed to be very close to W231 and Sport Pistol, both of which I have used in the past with no issues. I may pick up some OEM 9mm ammo as a test for this weekend's match. Will update after more testing. TIA Choking session last night.
  7. I have found it to be a lot easier to take the b/f off, hang it onto a 1 gal bucket with ammo in it for ballast on the bench, and let bullets drop into a box. This way I can run it as long as I need and easily watch the bullets and can easily make any necessary adjustments. Nice job on the spring mount. I had done something similar using a rubber bungee hook some time ago, but have reverted back to the good ole rubber bungee. Will have to do this mod.
  8. Interesting. Been running a Hyperfire Comp for some time, never had any issues with the pins.
  9. I put 3-4 layers of tape on the top of the spacer. Seems to do the trick. In the mean time, called Dillon, they are sending an oversized spacer. Will see how well it fits.
  10. I found that on the interwebs. Was gonna try it.
  11. Those of you loading with a fine powder like Clean Shot, are you having problems with the powder bar getting gummed up? Looks like grainuals are getting smeared, causing it to bind up. Cleaned it and replaced with a spare.
  12. I'm beginning to get floaters as well. Love them dots, allow us old farts to stay in the game. I have the 510C green on my PCC, it works well for me. I usually keep it on the dircle/dot, allows quicker acquisition. Best of luck!
  13. Mags have been least of my worries. They have been very reliable, and seem to last a long time. If you need parts, ILWT is a great place.
  14. I have a Venom for my 45, found a cheap Vortex mount on Amazon IIRC. Works for me.
  15. Having shot SS for many years, I am a firm believer in sight pushers. Makes it sooo much easier to zero. I have one I think I got from Midway, but it wasnt cheap. Buy once cry once. A good one will last you a lifetime.
  16. Wear ear pro. What happens if you get a primer stack detonation? WHAAT?
  17. Yes, G2 is BT only. Love mine, sooo much better than my CED M2.
  18. About 140 PF. Previous load avg 1112 fps mv, was a 125TC @ 1.135. This was a 125RN @ 1.100. Same powder charge, 3.7 Clean Shot. Will chrono this one soon.
  19. I was testing new bullets in my GenII MPX this aft (Blue 125 RN), and thought I would try a new zero distance. I’ve seen a lot of questions about what distance to zero. And of course, it depends. It depends on what game you are shooting, avg dist, etc. I shoot only USPSA, and most bays/stages have the longest shot maybe 25 yds, which is probably pretty typical. The first pic is a 10 yd zero, second pic is 12 yd zero. The 12 yd zero allows basically a POA/POI at 10-15 yds. This was very enlightening for me. (All were shot from a rest. ) The 1.5” hold over for close head A’s should be pretty easy to do.
  20. Just started using Shooters World Clean Shot for 9mm Minor. Love it. Cheaper than Sport Pistol, W231, and waaay cheaper than N320. Shoots pretty clean too.
  21. Blue Bullets for me. Tried, BBI, Blues load with much less issues.
  22. 1. Upside down brass in tube. - Not sure if I have ever run into this. Watch the case feeder from above to see how cases dont get rotated correctly. I had a problem with cases getting jammed up where they drop out of the bowl. Sometimes a piece of brass would sit horizontally between upright case and the bowl, allowing the upright case to get stuck at drop window. I made a wiper out of a plastic bottle and taped it to the inside of the bowl, this wipes off the horizontal piece of brass. Has virtually eliminated this issue. 2. Brass bunching up at top of tube. Dillon sells a small plastic funnel. I had to trim it quite a bit to fit my 1050 Super case feeder, but it has eliminated this. https://www.dillonprecision.com/plastic-funnel_8_120_23633.html 3. Case jams between shuttle and shell plate. Sometimes a stronger shuttle spring will fix this. Highly recommend spring from Ammo Bot. Also, check to make sure shell plate is level with press, is not damaged, too loose, dirty, etc. https://immortobot.com/index.php?main_page=product_info&cPath=4&products_id=289&zenid=mtnm92oms1197guii36d76q7a7 4. Case jumps out of shell plate. See above. 5. Primers stick to pin. Grind a wedge to the pin, then polish all the rough eges off. If you have a small shop vac, you can take a 1 gal paint bucket to run the spent primer hose into, and a larger hole for the shop vac. The vacuum will help suck off the primers. Make sure the area around the press and the primer spent tube are sealed with silicone. Also, do not wet tumble brass with the primers in, and then dry the brass. The primer gunk will glue the primers in, and you will get a LOT of pull backs. HTH
