Velocity Wrote:I bought a Sinclair chamber length gauge a couple days ago and the dang gauge would have fell in the case if it wasn't for large rim.
The gauge diameter measures .262 and the once fire case I.D. is .2665
I looked at my instructions that came with my Sinclair chamber length gauge and it states to full length resize the case before using the gauge.
The instructions on the Sinclair webpage does state to use a fired case without resizing it first. You could use it that way if you used a neck only sizing die or Lee collet die.
