About this time last year I bought a 308 R25 from a gentleman that had owned it about a year. He did not inform me of any issues with it and I had no problems at all until last weekend when I pulled it out to check the scope zero for our hunting season.

I was using the same ammo that I have shot since purchasing it. That is a reload approximating the GI ball load using FN primed hulls (berdan primed), WC846 surplus powder, and a 150 gr Hornady spire point hunting bullet. From the beginning, this load shot very well, usually under 1.5 MOA and sometimes under 1 MOA. I don't keep up with round counts, but have probably fired somewhere between 60-100 rounds of this and killed a whitetail with it last season. Never once did it fail to function properly.

When shooting last weekend, the first 3 shots went as usual but when shooting the second group I had a round that wouldn't quite chamber all the way. Then I noticed that one of the fired brass had a pierced primer. I cleared the chamber, thoroughly cleaned the rifle and shot it again. after 3-4 shots, the next round again failed to chamber fully. I pulled back the bolt and dropped it and the shell went in. When I fired it, the extractor pulled part of the rim off but left the brass in the chamber. When I knocked it out with a cleaning rod, the body of the brass looked rough like it had been sand blasted.

I'd love some ideas on what exactly may be going on here. BTW, I shoot this exact load in two bolt action rifles and none of the three rifles have ever given indication of high pressure until the pierced primer.

I would immediatley stop using those "reloads"...you obviously got a problem with the ammo, not the gun...(until it blows up in your face). I would pull all of those rounds apart to save the components...check the reloading manuals for data, and start over again. Just because you lucked out the first time(s), doesn't mean you luck is gonna hold...and I'm no reloader, but common sense dictates something is wrong.

Just my 2 cents...
