December $487 prefit group buy, several barrels are a go

[The Guide]

But those slouchy shoulders… yes the AI fixes that but 6-284 is just a neck down with nice broad shoulders already.

Ya but quality 6.5-284 brass is hard to come by these days. Lots of options for the -06 based cases.

Which ones feed into 6-06 without any neck turning out of curiosity?

30-06 has good brass but would be multiple steps necking and likely turning.

25-05 would be simple neck down but doesn’t has lots of good brass does it?

270 and 280 are both longer iirc so not a simple single stage neck down.

Am I off base on those or forgetting any?

Also 6-284 dies I know are readily available, not sure on the others.

It's a long shot but maybe a few others will think it's cool and jump in with me.

Tikka .750 Taperless contour threaded 5/8 x 24
Cartridge - 284 Winchester
Throat - .139" FB? (The GAP Match reamer from PTG shows .139" FB, but I'm not sure what PBB has on hand?)
Length - 20"
Twist - 8

PBB only lists the standard 284 WIN which in SAAMI form has zero freebore. I have seen some other guys on here that have got this chambering from them and there is enough freebore to run the longer heavier bullets where they like to be so they must have something like this GAP Match reamer. Just trying to run the 162 ELD-X so nothing too crazy. I think that is the ideal weight range for the 284 WIN in a hunting application.

There was a maker of 6mm-06 headstamped brass. Everyone is out of stock right now. It is supposed to be a limited run yearly. But to your point, yes there is a bit of work to make 6mm-06 or the AI version from Lapua brass.
