8.6 blackout. You guys got the big 338's. Per Ron Spomer, "8.6 Blackout: Weakest 338 Ever"

PTG is supposed to ship my gauges this week, I have two barrels ready to go. Going to be the bigger brother to my 300 BLK bolt action.

Have you seen the Maker's 350gn specifically for it? Next to a 250gn SMK and a half-modified 6.5CM case for scale:

I was reading that necking up the the 6 GT brass to 338 (multi-step, 7mm, .308, to .338) is the easy button. Supposedly just neck up and full length resize. Maybe a little trim. I haven't vetted it out yet. I have 200 rounds of loaded ammo (Gorilla ammo: 210gr tsx, and 285gr subs) and then a pile of 300gr SMK's.

PM me if PTG lets you down. I have the go/no gauges. I'll lend them out to you.

I like it, how does it shot?

Appreciate the offer!

I'll have to look up that easy way. I have a couple hundred random 6.5CM cases I'd planned to use for this - so far I've set up a T7 head with a carbide 6mm to 308 neck up mandrel, a 338 mandrel, then a Lee 8.6 die with no button in it. Used a WFT trimmer to do the bulk trimming and knock them back to just over max length.

Once I get the barrels set up I'll figure out the headspace using Redding comp shell holders and run them trough a second sizing die for the final fit. I have a couple cases cut short to measure actual chamber length with the Sinclair's gauge to set the final trim length after that. It's a decent amount of work but I had the brass and the time waiting on parts.
