Hornady carbide expander in RCBS die question - AR15.COM
2011-10-20u2002·u2002Thanks. I have the Hornady carbide spindle that I bought for my RCBS dies in .22-250. The carbide button measures .222' with my nothing-fancy no-name $20 caliper. For .223 and .22-250, or anything using .224' bullets, the expander should measure .222' (.002' of neck tension is what you are after.) Posted: 10/19/2011 6:09:48 PM EDT.
