You need a 5/16 × 36 tap and a fired case from your chamber.
I dont bother buying the Hornady cases for SAAMI chamberings anymore, their headspace is always short. Plus I can make my own my wildcat oal guages.

I agree 100% been using my own cases for 10 yrs now. But you will have to likely order the tap as its an odd thread typically found in stores.

Right, this tap will not be at your local hardware store because Hornady wanted to keep me from doing what I've been doing.

Tried one shot with the 28 out at 1240 yards today in 30 mph wind didn't think I'd pull this off in that wind haha.
