While organizing my dirty brass prior to reloading I came across some rounds that I'd stuck back into the ammo box. Since beginning this journey 3 months ago I find myself paying a lot closer attention to cases, and especially recovered cases from my loads. Thus far I hadn't noticed anything unusual, but when depriming these last 15 rounds I noticed that all of the primers looked a little bulged. At first I thought that it might have been one of my own reloads, but then I remembered where I'd just pulled these shells.
I still had a fired shell from my dirty brass, a Blazer 9mm, and decided to document my find with photo evidence. It's likely that I've seen this before, primer bulge before, and just never paid it any mind. My current suspicion is that Fiocchi USA 9mm may be loaded a bit hotter than anything else I'm shooting.
Another observation...the Blazer case measures 0.38" at every point along the length. The Fiocchi measures 0.38" at the bottom, top, and most of the length, but 0.27" from the head stamp the case widens to 0.39", which further supports by belief that this brand produces more pressure.
It is 9mm LUGER, 115 Grs. FMJ...as was the Blazer.
