Most of you guys know that I do a lot of machining. Well, I recently started working with an FFL07. I was initially just supposed to be doing barrel threading, RMR cuts, stuff like that, as I never really wanted to be a gunsmith for a variety of reasons, not the least of which is that I have my own 2 businesses to run and kids to raise, so don't want to be spending countless hours in his shop working on equipment I don't like as much as my own. But I kinda got nudged into doing more, and now I'm building high dollar bolt guns on actions like Badgers, Deviants, etc. with equally expensive barrel blanks. He's ponied up for the proper PTG match reamers and bushing sets, and holding tolerances and turning out beautiful work is not a problem, but I want input on the general preferences from this crowd, as many of our customers don't seem to know exactly what they want aside from a really expensive range toy.
My 3 questions are:
How tight do you like your bolt to close (headspace)? At present, I'm treating it like a precision machinist, and that is keeping everything on the tight side, just barely closing on a go gauge.
What sort of crown do you prefer? My SOP is a .030" counterbored flat crown, and .002" bevel on groove diameter with a near-mirror finish. Fairly easy to do, looks nice, and protects the crown.
How long do you like your muzzle threads? Unless someone requests otherwise, I'm doing .625" length right now, except for rimfires due to threads longer than 1/2" bottoming out on baffles in some .22 cans. I have never seen or heard of a centerfire can bottoming on 5/8" long threads, but I certainly don't want someone coming back to us with that problem and needing a cut & re-crown or having to use shims, so if anyone is aware of a can that won't take threads 5/8" deep, I want to know about it.
Thanks in advance!
