284 win neck diameter

[TonyC]

I am having a 284 barrel done that has .190fb and a .317 neck. Looking at either using Winchester or Peterson brass. I know I will have to turn them some. But with a .317 neck what loaded round neck diameter should I be trying to get. Any help would be great thank you !!

Mt.Boy,
The current Peterson Winchester.284 brass that is unturned has a loaded diameter of .316”. The PTG F open chamber reamer measures at .320” with a free bore dimension for the 180gr. Berger’s. Just something to consider..

I think the math is off a bit earlier in the thread. .317 minus. 005 is .312

I run a .315 neck and my loaded rounds are .310

Yeah I was looking at clearance on each side.

You'll need to turn the Peterson for sure, and it's damn good quality brass. My loaded rounds are coming in at .3165 and I went with a .321 neck as I hate neck turning. Oh yes, I run a .188 freebore and can jump the 184gr hybrids no problem.
