[QUOTE="LapuaMile, post: 552373, member: 30436"] I realize that it has been years since this post was made, but I came across an interesting discovery this weekend, so I thought I would share. I was shooting at a long range course, 1,000+ yards shooting both .308 as well as .338 lapua. I had shot over 100 of my .308 rounds, loaded 175 Berger vld bullets right out to the lands, and all of a sudden I started blowing primers. I knew that my loads were precise, and this wasn't a powder issue, as I had loaded with a computerized powder trickle. Long story short, my ammunition was wet, as it had started raining. I dried off all my cases, and ran a few dry swabs down the barrel.... Voila... No more pressure signs or blown primers. Moral of the story.... If you are already shooting a slitly hot load, with bullet seated out to the lands, the additional water on the case creates major pressure increases. Postulate that this is either due to the volume of air that the water displaces, or maybe the water drops heat so fast that they turn to steam, next creating a mini pressure cooker. Either way, I was skeptical until I dried things out and the problem vanished. I hope this helps anyone who has struggled with this mystery. [/QUOTE]
