Hi all,
I've been noticing something funny in my 300wsm cases. I've been loading them with Fed 215M match primers. Last time around I decided to try the Remington 9.5m primers as I've had good luck with them in the past (and have a bunch lying around).
I found that they went in too easily, and that I could knock them loose just by holding the case at an angle and wrapping it against a hard surface (they would actually fall out).
So, I went back to the Federals thinking the Remingtons might have a slightly smaller diameter. Then I noticed that while the Federals don't knock loose, they are going in much more easily than they used to (and I've only loaded these cases a few times).
So, it appears as if the primer pockets are expanding widthwise, which is nothing I've ever seen happen before. Is there something going on that I should be worried about? Is this a sign of excess pressure? I've heard of cases blowing primers due to excess pressure (and saw it start to happen with a 300WM I was working with a few years ago). But this is new to me.
I clean the primer pockets of carbon when I reload them, but I don't ream these or anything like that.
Thanks,
Ben
