Thread: .284 Chambering & Freebore Specs

Yep, you want to seat pills out long to get best out of the 284. Make up a dummy round with your projectile of choice seated so the end of boat tail is just below the neck/shoulder junction. In your case choose the longest pill you intend running 162ELDx . In my experience this should end up somewhere around 3.120 or maybe as long as 3.150”
