gas leak

I noticed a discoloration on the long beard spent hulls I shot today. Looked burnt around the top and about 1/3 of the way down one side.It was on every one of them and not on any other shell I shot. Anybody else see this? May be just the overboard mossberg. Don't seem to be hurting anything.

Just went and checked.  I fired 10 of them Saturday with a 935 and do not see this on the hulls I shot.

Thanks skeeter. May be time for a deep cleaning. It was last year before season when it got a GOOD cleaning. don't know why it just does it on those.

Me and a friend shot some long beards the other day out of our 870's and the hulls looked the same way like they were burnt

[surehuntsalot]

Out of my Mossberg the LB shells looked normal after shooting to me.

Same on the ones I shot...reason being the top that looks like a normal folded crimp blows apart when the shell fires.

I did notice that the opened crimp end on the spend hull does not look like a round opening on a standard crimped shotgun shell.  After firing the end sits kind of triangle shaped.  Now obviously it opened up round to let the wad out, but after firing it shrinks back to a triangle opening where as a standard crimped shell remains with pretty much a round opening.  Don't think there is any significance of this, just odd.

I didn't notice it

I'm not sure but I do believe they are roll crimped.  I just shoot a couple of them for the first time yesterday after I got home from work. 

[Skeeterbait]

Yes, there is a thin plastic disc that covers the shot.  Then the edge of the hull is rolled all the way around to hold the disc in place.  Nothing new, I remember buying buckshot 30 years ago loaded this same way.

Their Partition Gold slugs do the same thing out of my H&R.  They shoot just fine, though.
