.22BR./DASHER neck dimensions

I am in the process of ordering a .22 Dasher reamer from
Pacific Tool. At this time I do not load for .22's.

I would like the finished cartridge to be a no turn,
with .002" clearance. What I have done is taken 3 pcs.
of new 6mmBr.lapua brass and sized it down to .22 and
seated .22 bullets.

What I've ended up with is a unturned neck dim.of .2525"
with a bullet. That means I should order my no turn
reamer at .2545 /.2550 ?

I'm looking for advice or opinions, Please feel free to
share your thoughts.

I'd go .255 personally -- same reason im going .272 for a .269-.2695 loaded round :thumb:
