Ha, yes by that method I need only a eighth to a quarter turn in the one. It showed up strapped & wrapped to a board in a box. Well done by Pacific tool & gauge.
Did some initial shim tests. Placed foil between barrel & receiver face to gauge how far out a slowly eased in case was off. I was able to change the headspace that way but didn't fire. Measuring the shims it's off .001 on the pistol barrel and that matches the sized & measured brass chamber tests.
I've grown accustomed to using 10/30 with the throating reamers. The cutting oil let them bite to much for my taste. Only drawback I found was the chips wanna stick & you have to clean more.
I did a couple throats with nitride. The one Swenson bbl had some really tough stuff. The lone wolf tough but not as thick. Didn't dull the reamer but I went slow, by hand, & cleaned every few turns. It took 3 hours.
They will sharpen the reamer to, unless we get really crazy it shouldn't be ruined. We'll see, one is stainless, one is supposed chromoly.
