What ammo was that?

Be hard to get that kind of pressure with just an overcharge with most powders. I load IMR4350 in my 25-06 and run a compressed load with no issues. Just out of curiosity can you weigh the rest of the loads from that box separately? I’d want to identify the cause before I even started repairing the rifle.

Believe it not, I know “someone” that mixed up ammo during a range session and mixed in 308 with 270s.

The savage action saved my, I mean someone’s ass.

Yep. That's a little beyond just a shiny ejector mark on the case head.

This has me curious.

So thanks to Gundoc for helping me out. Turns out that when I grabbed the ammo someone (me or one of my kids) had dropped a Hornady 6.5x55 back into a box that I thought was a brand new box of Hornady .25-06.

When I loaded to shoot at the CMP Range in Talladega my first round in that gun was a 6.5x55 and the case separated and lodged in the chamber. The extractor got stuck due to the ammo pressure but I got extremely lucky and didn't damage the rifle at all. I'm thankful for that because you're not able to get a whole lot of replacement parts for these from Browning these days since they don't make it anymore.

Boy you did get lucky. Glad it wasn't any worse. Good reminder for us all to be cautious and double check. This is the exact reason I don't own a 300 Blk or a 270 any longer.

Yeah we have had an ammunition identification class at the house and since we have a few calibers in our hunting rifles we are making sure that everything is completely separated out into different ammo boxes and no more dropping into an open or available box when we are done shooting.
