well had a strange thing happen yesterday on the range
was sighting in my 25-06 using ammo that I loaded up years ago and 2 out of the 18 rounds were way over pressure, very stiff bolt lift, needed a chunk of wood to beat on the bolt handle to eject the round, had some brass flow into the ejector (Tikka 695) blew out the primers, primer pocket is oversized. The rest of the ammo was fine, I don't understand how this could happen. I know that I weigh every charge when loading, and the load is under the published book data.
So asking for opinions, could this be a case where the ammo has been rattled around for 10 or so hunting seasons in the plastic box on the quad and in my jacket pocket hot and cold enough to cause these 2 rounds to have the powder break down effecting the burn rate enough to cause the over pressure. When you look at the rounds in the box you can see that they have marks on the brass from where they have been in contact rubbing the plastic box edges.
I normally use a plastic box of 20 for hunting and it rides with me in my jacket pocket as I use rounds I replenish the box from my reloading stock (box of 50) and I am not really concentrating on using oldest first so it is possible that some of the rounds in the box of 20 are significantly older then others.
