Hi Corn
Not say you did any of this below.
Some other things that cause overpressure are:
1.) Case Length - What length was your cases (before you loaded them) and had they been trimed to length? I have seen a gun explode (alot worse then yours) where the shooter failed to trim his cases. He had only just started reloading 6 months before and I was looking at his cases and we messured a few and they were really long, I asked him about trimming his cases and he had no idea about what I was talking about. LOL
2.) Bullets Touching Lands - I see so many people saying they are shooting maximum loads with the bullets seated out so they are touching the lands. There was an article years ago where they were measuring and testing ammo that where loaded so the bullets were around 50 thou off the lands and other ammo were the bullets were loaded out to touch the lands. The ammo with the bullets that were touching the lands were averaging around 5000 PSI more (and up to around 10000 PSI) then the bullets that were 50 thou off the lands. Having the bullets touching the lands causes a spike in pressure that can become dangerous when you are loading "HOT" ammo. If you are loading ammo with the bullets touching the lands and you are having pressure signs try seating the bullet to be 50 thou off the lands (I load nearly all my ammo so the bullet is around 50 thou off the lands).
