Away for a time, sickness..
Here is print with chamber reamer specs for the
416 HSM chamber..There are 3 base sizes we have,
depending on actions used. Got reamers for all 3..
Got cases for all of them..
Our cases are public domain, so that is why I post
info and specs. To help guys do their own setups.
