Schultz77 Posted April 6, 2019 Share Posted April 6, 2019 Hey guys I have never had anything like this happen. Was testing a light recoil hand load for competition this weekend. Was doing a bill drill, recoil was very light anyway so didn’t feel anything weird. On my last shot gas blew out the sides scaring the piss out of me. After checking my hands I realized everything was still there I just had gsr all over them. The brass had blown in half and the base was really deformed. A little was gone. Nothing in the barrel but I knocked the base of the brass out the other half is still there. What do you think happened? Squib the shot before? I dont think it was a double charge because it would have probably over flowed. What does it sound like to y’all? And do you think I should have the gun inspected before shooting again?

GrumpyOne Posted April 6, 2019 Share Posted April 6, 2019 What gun, what caliber, what load, what brass? Need more info. Link to comment Share on other sites More sharing options...
36873687 Posted April 6, 2019 Share Posted April 6, 2019 I’d say u got a step case Link to comment Share on other sites More sharing options...
Schultz77 Posted April 6, 2019 Author Share Posted April 6, 2019 9mm S&W proformance center 9L, 147gr xtreme.356 with 3.2 gr titegroup. Mixed brass and the stamp was blown off. Link to comment Share on other sites More sharing options...
GrumpyOne Posted April 6, 2019 Share Posted April 6, 2019 Doubtful it was a squib. If it was, it likely would have bulged the barrel, which you would be able to see and feel. Most likely a bad case, or as said, a stepped case, which resulted in an overcharge. I can't say this enough, look into each and every case as you are reloading, before you seat the bullet. I can't load a stepped case...using Dillon dies, it stops at the resizing die. Link to comment Share on other sites More sharing options...
mwray Posted April 6, 2019 Share Posted April 6, 2019 It could’ve been a double. Should be plenty of room for 6.4 grains of powder behind a 147. That or it was stepped brass. Is there room in stepped brass for a 147 at mag length? Link to comment Share on other sites More sharing options...
Schultz77 Posted April 7, 2019 Author Share Posted April 7, 2019 Think I should get my pistol checked out by a gun smith? Link to comment Share on other sites More sharing options...
Postal Bob Posted April 7, 2019 Share Posted April 7, 2019 Many things it could've been including simply brass fatigue. That particular shell might've been loaded and shot in a 9mm major gun. The brass from such loads doesn't last long. Link to comment Share on other sites More sharing options...

drewbeck Posted April 7, 2019 Share Posted April 7, 2019 Case head separation, or it’s like a squib but it’s actually a detonation, meaning it’s a super light charge that had enough free space/air in the case to detonate vs burn like a normal rounds does. If you go below the minimum charge weight it can be equally as catastrophic if an explosion as going drastically over the max charge with a fast powder. I’d rather have a squib any day of the week that a 1 grain (light charge) of titegroup go off.

Schultz77 Posted April 7, 2019 Author Share Posted April 7, 2019 Thanks for the help guys. I have been reloading Rifle for a while but pistol is new. I usually don’t reload but about 20 at a time at most when I take the dog out so I usually take my time. Link to comment Share on other sites More sharing options...
Schultz77 Posted April 7, 2019 Author Share Posted April 7, 2019 Do you think if it was a stepped case I would have been able to find this if I had plunk tested every round? I usually do every 5th round. Link to comment Share on other sites More sharing options...

BigMoneyGrip Posted April 7, 2019 Share Posted April 7, 2019 Did you get a centered hit on the primer? One firing out of battery will do what you described. Link to comment Share on other sites More sharing options...

Primer was gone but the brass left in the barrel is fully seated it looks like. And is still stuck there. Link to comment Share on other sites More sharing options...

I would put the barrel in the freezer for a few hours and use a dry bronze bore brush to remove the stuck half of the case, before the barrel has a chance to warm up. Insert the brush part way, twist and pull it back out. The case should come out on the brush, because brass will expand and contract more than steel with varying temperatures.

ltdmstr Posted April 8, 2019 Share Posted April 8, 2019 Most likely it's due to a stepped case. If it was a double charge the case would be intact but blown out at the bottom. Link to comment Share on other sites More sharing options...
echotango Posted April 8, 2019 Share Posted April 8, 2019 I'm playing around trying to make a die to find stepped brass in the primer location on the 1050. Parts get here this week. Link to comment Share on other sites More sharing options...

Not to totally contradict but just spray some gun oil, wd40, or other lubricant in it to soak outside the case and use a brush, pick, tweezers, etc to remove. the case expanded and wedged itself inside the chamber during firing but cools and shrinks after firing. It happens every time you fire a round, you’re just missing the rim and extractor now. There’s carbon that’s making it sticky Link to comment Share on other sites More sharing options...
