Selling 3 unopened boxes of Peterson 300 Win Mag (Long) Brass (150 total). This is the newly released version. I am selling it because I found some more ADG and do not want to have to redo load work up. Asking what I paid - $225 TYD.
Second root cause identified, brass was smacking the parallax knob of the scope during ejection. I’m running an NX8 and it sits lower than the previous scope I had on the rifle. I put an O-Ring around the knob and this protects the brass.
All the brass I loaded in April up above is toast in the primer pockets. About 130 lasted 4, 20 only 3 firings. I’ve still got 200 of the Hornady stuff, so won’t be trying the ADG just yet, but good to hear it lasts longer.
