If I can get 1/2" out of my hunting rifle, I'll be jumping up and down with a huge smile on my face!!
Just made me a little nervous that a custom action was that out of square as Mr. Kampfeld described.
If you can't get 1/2" out of a full custom hunting rifle, the 'smith wouldn't & shouldn't get paid until you do, no matter what action it's on, and especially if HE recommended.
If he won't do it, I've got 2 on M70 blueprinted actions that will, and one is a 300 Win., that I'll sell to you.
