1911 guys riddle me this brass issue:

Problem Solved, check page 5 for the findings.


I was reloading some 10mm brass so I could shoot my new Delta Elite some more when the ram would not go all the way up to the die.
Pulling the brass out I noticed a bit of an issue:

I have to admit that in 20+ years of reloading with probably a hundred thousand or more rounds loaded and numerous "shoot until failure" tests, this is the first time I have encountered this. I've seen bulges on one side from shooting through a Glock stock barrel, but these rings go all the way around.

This load is 8.4gr HS-6 under a 180gr Ranier Plated bullet, squarely in the middle of Hodgdon's charts, and this is loading number 8 for this brass. The brass is some Russian headstamp, looks like "nny". Not all did it, but I found 5 out of the 8 I shot that had it.

What say you, think it'll buff out? Seriously, is this something that is common in 1911s? Is there a timing issue that is off? I know next to nothing about 1911s.

no a setup right 1911 would never do that.......there not head spacin' or firin' out of battery......you have gun trouble!!!!!!!!....is the sear disconecter workin'?

It's not out of battery as far as I can tell, the slide is completely forward, is there something else I should be looking for?

are they headspacin' to the back end of the hood?

 

[IndyGunworks]

is there alot of slop in the link pin? possibly a timing issue where the slide is coming back before the pressure is at the safer lower pressures?

 

[IndyGunworks]

new gun? or at least new to you?

 

[shibumiseeker]

Brand new. Possible I did not reassemble it properly?

boy if that's it.....it's way and i mean way out of time....does it do that with factory ammo?

how about a pic of the barrel with a rd in it.....out of the gun...

I'm going to check.

9MM Size Die???

What did the brass look like before being sized?? Anything different/strange??
Almost looks like they were 9MM sized??

Are you sure it's a 10mm??? wonder if a 10mm would fire in a 45 cal barrel??? If it could I bet it would come out looking like that!

i thought all Delta's where 10mm....maybe it got a 45 barrel by mistake?

 

[shibumiseeker]

No, it's a 10mm and the ammo was sized correctly. I'm leaning towards a brass issue. I took my Glock 20 stock barrel, my LWD Glock 10mm barrel and the DE 10mm barrel and compared them side by side with a brand new factory round sitting in each and they all headspaced correctly but the DE barrel leaves a bunch more of the web of the brass exposed. I'll get a pic up after dinner.

I think this means no nuclear loads for the Delta Elite. Time for a brass life experiment with this gun.

 

[ghitch75]

but if it was the brass how in the world are they not gettin' stuck in the chamber????

 

[shibumiseeker]

 

[ghitch75]

i don't own a 10mm......man there's a lot hangin' out on them....it that right?

 

[shibumiseeker]

This is after firing, it's sized properly before it's fired and this is a Russian brass with 8 loadings on it. Second time fired through this gun.

 

[ghitch75]

i see why there not gettin' stuck now......need to see another 10mm barrel with a round in it.....maybe it shouldn't be hang out that much....maybe it got cut wrong at the factory...

 

[billybob44]

I know it is not-but-the barrel on the right almost looks like it was cut for the .40 S&W??

Sure that aint the start of case head separation? I've never had it happen with any of my loads, so I'm just taking a stab in the dark.

Oops I just seen the pics of the loads. Didn't see there were 2 pages.
