My friend is having some problems with his 9mm 1911. I think it is a fusion forearms? The gun had 100-250rnds through it during all this, he was working on getting it broken in.
In addition to the issues listed, the safety plunger was not properly staked. the front sight was loose in the dove tail and moving around. And the set screw for the rear sight came loose. Not a great start, he's pretty unhappy with the gun. Experienced shooter. But I digress, onto the main issue.
He contacted the manufacturer and is sending it in for service.
A couple weeks back we went shooting and he was having some cycling issues and was swapping out the return spring. During this time I noticed the cases were bulged at the top pretty good. He though the spring was allowing it to unlock too early.
A couple days ago we went out and the gun seemed to run ok. Shot 3 factory ammos, some Federal Syn tek 124g, some underwood 90g lehighs, some Blazer brass 115g (which did not cycle reliably) and some of my reloads, 125g coated lead with a mild load of N340 at about 1050fps.
I collected the brass and when I got home started sorting, checking head stamps, to make sure I had not grabbed any 380 or 40s. I found 3 with pierced primers. Also they seems to have a ledge on the rim on all 4, although is it less noticeable on the nickel casings. One of the casings has a heavy swipe on the primer.
After looking again all the cases were bulged at the top as well
all the primers looked flattened, but not necessarily flowed.
As near as I can tell none were my reloads
The underwood puts a Significant crimp on their ammo, which did not seem to come out...
Trying to see what I can learn from these pressure signs as a reloader, some odd stuff I have never run across.
