b18prl Posted November 27, 2014 Share Posted November 27, 2014 I kept getting this jam recently but only happened while I'm shooting a match so I had no time to diagnose it. Today it happened again first time on my practice. Anyone ever had this jam before on Stock2? Link to comment Share on other sites More sharing options...
bayougump Posted November 27, 2014 Share Posted November 27, 2014 I honestly have never had a jam in any of mine, few times it was mag or not case gauged ammo. They make a more powerful extractor spring, couldn't hurt if you're having these jams on more than one occasion Link to comment Share on other sites More sharing options...
kneelingatlas Posted November 27, 2014 Share Posted November 27, 2014 Are you chamber checking your ammo? What weight recoil spring are you using? What weight bullets? Link to comment Share on other sites More sharing options...
b18prl Posted November 27, 2014 Author Share Posted November 27, 2014 Bayou 147gr with 8lbs spring and it happens with random mags. I chamber checked. Link to comment Share on other sites More sharing options...

Nealio Posted November 27, 2014 Share Posted November 27, 2014 (edited) That looks like a short stroking issue. Causes: Using a coarse powder that doesn't meter very consistent or splashing the powder out of the case when you index a progressive press. Gun isn't broke in yet, so empties are barely clearing the ejection port. Then any light charges would cause this. So what powder are you using, how much, and how many rounds on the gun? Comment back and well get this fixed up Edited November 27, 2014 by Nealio Link to comment Share on other sites More sharing options...

Comment back and well get this fixed up I was going to ask the same question along with extractor springs. Make sure it's not gummed up or anything like that. Although not the same as a rifle, I was having the same type of malfunction on one of my ARs and it was short stroking. I changed what I needed to change and the problem went away.

b18prl Posted November 28, 2014 Author Share Posted November 28, 2014 It happens with both WST and N320, let see..... I bought the gun new in Summer of 2013 so my guess is around 10-12000 rounds through it. I always loaded the same with 147 Bayou with 3.5 gr if WST for practice and 3.3 gr of N320 for major matches.

b18prl Posted November 28, 2014 Author Share Posted November 28, 2014 Ohhh and I load with 650 using my fingers to slow down the shell plate so no spillage there. Link to comment Share on other sites More sharing options...

johnbu Posted November 28, 2014 Share Posted November 28, 2014 Are the mag springs getting weak? Link to comment Share on other sites More sharing options...
R.Elliott Posted November 28, 2014 Share Posted November 28, 2014 (edited) Eliminate variables. Check Extractor hook, check Extractor spring, clean Extractor channel, check ejector strike-point. Chrono loads Is the empty case striking the lower wall of the ejection port? If so, it will bounce back up into the path of the closing slide. Edited for autocorrect.

b18prl Posted November 28, 2014 Author Share Posted November 28, 2014 My gun ejects the spent cases around 1 o'clock position since the day one. Link to comment Share on other sites More sharing options...
BiggMike Posted November 28, 2014 Share Posted November 28, 2014 (edited) For giggles try moving to the next recoil spring up. I had the same problem with my Stock III and I went from a 7lb spring to an 8lb spring and the problem was solved. I hate to see you start changing a whole bunch of springs and possibly introduce more problems. Edited November 28, 2014 by BiggMike Link to comment Share on other sites More sharing options...

jmbaccolyte Posted November 29, 2014 Share Posted November 29, 2014 (edited) My recoil springs are playing hide and seek while I'm not watching them? Damn, that was the most stable part of my life...
