7mm PRC bushing size

[nomrcynd]

I’m going to order Redding Dies-I Hage never loaded for 7mm. Starting with Hornady Brass, but hopefully ADG will have some soon. Any recommendations on bushing sizes to order?

I would have .305 to .309 for whatever neck tension you are after.

I’ll measure some loaded rounds as soon as I can. The print shows .317 loaded. If that’s the case you’ll want .313-.315ish.

I measured mine loaded at .310.

I am guessing Hornday is on spec but before I recommend any bushings I will check.

I would be interested to see what you get too.

Hornady brass is .314 loaded.

That is a good amount of difference between Hornady and RCC but a good reason to measure loaded rounds in the brass if you go with a bushing for setting neck tension. I switched to mandrels on the last two rifles and go off the bullet now. A little simpler for me.

My factory 7mm prc ammo in the 175 eldx precision hunter measured .3125 to .3135 on the first 20 I did. Gonna start with .311 bushing and see how it goes
