amen to that, nice info

I have been having some issues with Winchester LR burning small holes at the edge of the primer cup and the primer. Had to toss the brass and replace 2 bolt faces where they had been pitted from the flame. Shoot the the same load using brass from same lot with CCI 200's and no issues. I think that article explained why
 
I had to weigh in on this thread because of my moniker.

I did not type it. I cut and pasted it. Don't remember where I got it but it's in my archives.

I actually had to delete some of the article because it went beyond the 30,000 character limit. I deleted the 50 BMG section.

I'd be interested in reading all of it, If you have the time, could you send the deleted stuff to me in a (or multiple) PM?

I've already saved the above stuff. Thanks

Flashhole,

It looks like you escaped reading the board policy on posting copyrighted materials. Due to past lawsuits against boards for copying articles, this is not allowed on the board. It's too bad, but to avoid being sued, it had to be done. Probably a maximum of a couple of paragraphs will fall under Fair Use Doctrine, but that's all you can do other than direct people to the source information.
 
Note that very large (1/8") primer flash holes (aka, vents; see SAAMI glossary) usually exist because the very high brisance of the DDNP sensitizer in non-toxic primers would back the primer out of the pocket so hard it would leak or pierce. You still find those cases, but usually, they are small primer pocket in 45 Auto now, and the old large primer pocket NT primed cases have disappeared. The small ones work with a 0.080" flash hole, and that's why a lot of small primer pocket 45 Auto is around now.
