Barnard "S" action Cone Angle

[Bob3700]

Anyone have a bolt print for the Barnard "S" action that shows the cone angle? Just purchased an "S" action and am acquiring the info to put a bbl on it.

Early ones where 45, Later ones are 30.

Haven't fondled but one of them....at Stan Wares shop years ago. There was some discrepancy even then as to what Barnard had published and what it was supposed to be.

I know at one time PTG made a reamer specifically for the Barnard cone breech.

For what it's worth....-Al

Put the bolt nose against your compound and swing it around until the bolt body is parallel to the ways.

PTG makes a Barnard breech end reamer but they don’t I’d the degrees. Is the “P” cone angle the same as the “S”?1
