b2alpha Posted June 22, 2020 Share Posted June 22, 2020 Has any seen case bulging or firing out of battery like this from their Legion or X5? Quote Link to post Share on other sites

ChuckS Posted June 22, 2020 Share Posted June 22, 2020 And you may want to look this one over also. This thread talks about the gun and possible reloading problems but worth a look, I would think.. Good luck! Quote Link to post Share on other sites
dansedgli Posted June 22, 2020 Share Posted June 22, 2020 Here's some of mine. Quote Link to post Share on other sites
ChuckS Posted June 23, 2020 Share Posted June 23, 2020 Is the barrel on the left your sig barrel? Quote Link to post Share on other sites
dansedgli Posted June 23, 2020 Share Posted June 23, 2020 Yep. Sig on the left, Glock 17 Gen 4 in the middle. Shadow 2 on the right. That's an early silver barrel. I bought a newer sig x5 non legion with the black barrel and it was the same. I thought it might be the gun so I bought another one and it did the same thing in the first 10 rounds. Much disappointment. I had to use a slower powder or sort my cases by headstamp just for my x5 so sold them both. Quote Link to post Share on other sites
ChuckS Posted June 23, 2020 Share Posted June 23, 2020 Wow, it looks like your bullet is hitting the rifling. Are you using chubby 147's by chance? It looks like a very shallow chamber. The plunk test will tell. From your pic, it looks like fail. As to why the sig would fire that far OOB, is another question. Quote Link to post Share on other sites
dansedgli Posted June 23, 2020 Share Posted June 23, 2020 Bullets arent hitting the rifling. They plunk tested fine. It isn't out of battery either. The case head is flush with the barrel hood in that pic. The case just isn't supported well. Quote Link to post Share on other sites

RJH Posted June 23, 2020 Share Posted June 23, 2020 So, really it is not a case of firing out of battery, it is a case of s#!tty barrel design. Least that is my conclusion Quote Link to post Share on other sites

b2alpha Posted June 23, 2020 Author Share Posted June 23, 2020 (edited) Hi y’all, In sent pictures of brass and head stamp(to see primers) to a Sig expert. He definitely thinks it’s a pressure issue. These were 125 and 147 coated bullets, sized 0.355), with Clays only making 125 power factor. I have been seating them short, 1.100-1.115”. They do pass the plunk test. Rounds seated at 1.130” also passed the plunk test but we’re a little sticky when ejecting the last unfired round. Primers are Federal small pistol match. Edited June 23, 2020 by b2alpha Add additional fact. Quote Link to post Share on other sites
dansedgli Posted June 23, 2020 Share Posted June 23, 2020 A sig expert wants to blame the ammo and not the massively unsupported chamber? Maybe go to a real gunsmith instead. Quote Link to post Share on other sites

s2000red Posted June 23, 2020 Share Posted June 23, 2020 Here are two of my Sig barrels. The black barrel is from a 2/2020 production X5 Legion and the silver one is from an early X5 (like the one the OP posted). Notice the silver barrel has a taper around the chamber and the new black barrel does not. Quote Link to post Share on other sites

Could you please do us a favor and put an unfired round in each of those and photograph them like the image in the 4th post above? I know I would like to see how much case is external to the chamber. Thanks! Quote Link to post Share on other sites
s2000red Posted June 23, 2020 Share Posted June 23, 2020 (edited) Hey Chuck. I know you asked for unfired but I had taken these earlier. I promise they are pushed into the chamber as far as they will go. Any others, just let me know. Thanks. Edited June 23, 2020 by s2000red Add info Quote Link to post Share on other sites

BARRYJ Posted June 24, 2020 Share Posted June 24, 2020 I bought a P320 Legion Monday. I was scared to shoot it after reading this post. I did a plunk test with three different reloads and everything looked fine. The round wasn't covered like some of my other guns, but it looked like the only part of the round exposed was the web of the brass. I shot it Tuesday with no problems. I'm happy with my purchase.

I’ve shot atleast 200k rounds through the X5 and X5 legion. I did have one extractor blow out a couple years ago. I suspect a double charge, but there is no way to be 100% certain. That said, IMO it’s a very reliable platform. ive never seen bulged cases like the above pics between 7 different guns. Edited June 24, 2020 by Rich406 Quote Link to post Share on other sites

I have been seating them short, 1.100-1.115”. Word on the street is that Clays can produce some serious pressure spikes in 9mm, especially when case volume gets low. Have you tried some factory rounds in there or just the clays reloads? Quote Link to post Share on other sites
jpm2953 Posted June 26, 2020 Share Posted June 26, 2020 I need to check my barrel out. I've got 8ish thousand through my legion and i reuse my brass 4-5-6 times? i have yet to see any buldged cases. Quote Link to post Share on other sites
