Ok, so I called Remington (ammo was early 90's vintage 130 grain Rem bronze point). They only back their ammo for 10 years (expected shelf life according to Remington). Note* I kept this ammo in a cool, dry place, sealed in a US Military ammo can for the past 2 decades. I have ammo from the 50's and 60's that still shoots fine. I guess with gunpowder, it's like rolling dice.
So, I'm glad the rifle is a Remington, as it was strong enough to take the hit without any damage, otherwise it would be my dime (and hide). I had our armorer (LEO), check it out as well. The bolt face appears ok, and I pulled the firing pin, ok as well. Damn strong rifle.
That brass was warped near the rim, I hate to guess what the PSI was, I'm betting well over 80,000 PSI, given how stiff that bolt was to open.
If I can get a photo posted, I will.
Now I have several boxes of old .270 ammo to dispose of, as I'm not going to shoot it through my cherished 700 BDL anymore. At least the brass is still good and my right hand is still attached to my arm!
Time to go out and stock up on .270's!!!
