Re: Pierced a primer on my 280 AI need info?
get win. brass, for all intensive purposes nosler is overpriced junk if your pushing it a bit, and from your velocity/barrel length numbers your running it pretty hard. My Gibbs runs 140's at 3240 fps with a 29.5" tube.
I tried nosler 270 brass to form 6.5 gibbs. I was blowing primers with the same fireform loads that the rem and winchester took in stride. I'll never use it again!
