300 Whisper Brass For Sale !!

[tp555]

Have you had any problems with the necks of the brass breaking off? I made my own batch from 223 mil brass.After about 5 reloads the necks separated at the
case wall to neck bend. It was easy to remove with a brush from the chamber. I thought this was because the once fired brass was hardened and annealing the neck area would solve this. brass was lc marked.I use rem 221 new brass now
and it is way soft the first time. Chamber is from a clymer 30/221 reamer which
I have used for years.regards.
