Hey,
I'm looking for some info on 284 Shehane chamber spec options to best suit a SA , while avoiding neck turning(neck up Lapua 6.5x284 cases), and possible case pressure issues as they relate recommended chamber neck OD and chamber freebore with the intent to shot a Berger 175 Elite Hunter .
I've kinda seen for the most part recommendations toward .317"+ neck OD and .200"+ freebore chamber recommendstions.
Cheers!
 
You could give Insite Arms a call and ask them what they recommend. They are spinning up a Shehane for me as we speak, plus I know several other F Class shooters who have got their Shehanes from Insite as well.
 
You would need a minimum of .003 neck clearance
Most cases are .0015 neck thickness per side + .284 would equal .314
.003thou clearance would be a minimum .317. Scott Harris runs a.320 neck
Can’t speak to freebore as everyone I know shoots the 180 - 184 Berger’s

Contact JGS or PTG for reamer specs
