While I was reading I came across a few paragraphs that explained the same thing happening and it was because he had put a double charge of powder when reloading. I very new to this kind of shooting and rifles, but its a suggestion. Glad your alright.

While it is possible to overcharge a .308 Win, the powder volume is usually large enough that a true double charge would almost certainly spill over the mouth of the case.
