I wonder if the "compound" throat is hard to get right because this problem seems to be epidemic.
I should also say the head space on this barrel was fine.

The chamber on that one was not in spec. Sadly there is at least one reamer maker who makes out of spec reamers and doesn't seem to care. Given some of the rough chambers I've seen outside of throating issues many barrel makers/finishers seem to use (or abuse) their reamers way past their usable life span. http://www.65grendel.com/forum/showthrea...asurements
