Sees Target (5/11)

  1. Sorry, not taking any gun work currently. Thanks
  2. That may be possible, but my experience is different from yours. I would set the feedlips on my mags before a match and when I checked them afterwards the settings had drifted. Now that may be from them being loaded to the max during the match as well as them being dropped on the ground, but fact is that the mags are made with much thinner metal than a 2011 style mag. Having owned both types of guns, and having tuned magazines on both I can say that the thicker steel construction of the 2011 mags are superior at holding a tune. Running a brush through mag tubes that hit the ground after a stage is a good idea from a reliability standpoint no matter what brand you shoot.
  3. Are you running a .40? Because that has not been my experience with the 9mm mags that came with the Czechmate, especially the big stick.
  4. I had the same problem with my Czechmate mags, tuning the mags will fix then temporarily. Unfortunately when they get dropped on the ground with rounds in them the tuning goes out the window. The real problem is that the CZ mags are flimsy compared to 2011 STI,SVI or MBX mags. You can drop those on the ground way more times than the Czechmate mags before they need retuned, like 30 or more matches worth, verses maybe 5 or 10 for the CZ.
  5. I used to have the same issue and just went to a hardened pin instead of the slide stop. No more issues. Hell I used to run a 6lb spring in my Gold Team lol
  6. 4.1 grains W231, xtreme 124 gr fp at 1.100 oal is good for 133pf. Very accurate as well.
  7. I really wasn't trying to rain on anyones parade, I just would rather say something than have someone go to a major and then be disqualified due to an overweight pistol. Of course I was unaware of the rule change so there ya go.....It's good that they are addressing issues when they arise and making changes to the rules.
  8. Ah new rules catching me by surprise, thanks for sharing that ?
  9. This is what it says in the book. From top to bottom: The CO addendum and the Production rules. Unless something has changed this is what I am going by.
  10. Yeah I had thought about putting some lead in mine, fishing weights most likely. Glad to see you have already tested it. The only thing is that If you shoot Production or CO you will be over max weight which is max 2 oz above factory posted weight. To be honest once you have a mag inserted it pretty much balances fine anyway, add some rounds and it is rear heavy.
  11. Ok cool, I was going to try 3 grains with a 147 xtreme but I may drop that a tenth. I was using 3.2 gr titegroup, 147 xtreme @ 1.130 and it was 139 pf out of mine.
  12. Yep it's a very well thought out package on the cheap. The 13lb spring is too light IMO for reliable feeding, maybe a 14lb if they make one? I put the small grip panel back on mine and that made the length of pull perfect for my medium sized hands. Dryfire trigger finger placement is automatic now, we will see if it holds when I shoot my next match. I have about 3 matches worth of 124s loaded until I can test some more 135s and 147s. I may end up trying some 165s with about 2.6 grains of titegroup and see how it goes.
  13. Actually the chamber on the Canik will allow 1.170" with a 147 gr round nose type bullet. The Flat points are .059" shorter than the 147 so they still drop in and spin @ 1.110" due to the generous throat in the factory barrel. The Canik barrel is 5.2" vs 4.75" for the CZ so that may account for the extra velocity and increased PF. This one is loaded @ 1.105"
  14. Did some load testing today and found that the loads I used at the match which were making 132 pf out of my CZ Shadow were making 139 pf out of the Canik. That load is 3.2 grains titegroup, 147 grain xtreme rn, cci spp @ 1.135 OAL. Temp was 90f, 400ft above sea level, 70% humidity. The ones that hit the power factor of 130 were: 3.2 grains W231, 147 gr xtreme rn, cci spp @ 1.140 OAL. Avg fps: 888 4.1 grains W231, 124 gr xtreme FP, cci spp @ 1.100. Avg fps: 1051 Accuracy was excellent with the 124s, very good with the 147s. Titegroup loads were 138 pf and above so those would need to be reduced. I'm going to start with: 3.0 gr, 147 xtreme rn, cci spp @ 1.145 - 1.150 3.4 gr 135 xtreme rnfp, cci spp @ 1.145 - 1.150 3.7 gr 124 xtreme FP, cci spp @ 1.100 I am guessing these will hit the magic number. I had one that was 123 pf and it did cycle the slide which amazed me. Of course ejection was about 6 inches from the gun but it shot and ejected all 5 rounds. I did a better job on the trigger today after a bunch of dryfire.
