I have approximately 160 300 rum once fired R P brass. I really need a RCBS precision mic in 300 rum. They are not in production anymore and everywhere I've checked on the internet is not available or sold out. Its a tool that is not used often, but needed to adjust the reloading dies for proper sizing.
I have some .... around 140 pieces. Most new some 1x only issue is most are loaded with 200gr. Nosler Accubond. If anyone is interested let me know and I'll get a actual count of what I have. IIRC it's all Nosler brass
