Dimension was listed as 10.16mm. I just measured an XTP with my "cheap" HF caliper, and got 10.14-10.16 depending on how hard I squeezed them. Most people agree that the reamer should be a few thousandths smaller to allow final polishing. If they cut a mirror finish I guess they would be good to go.

those look awesome but like you said cc it would be nice if it was undersized a few thousandths to allow for die polishing....

for $8 if might be worth it to get it and see what it is, maybe take it to a grinder and take off just a little off the head, a little off the tip to get a 0.25" meplat, and it might just work... this guy has them in 6mm (0.240/243win) and other sizes as well...
