Sorry that you're too dense to understand anything about chambering rifle barrels. You probably don't own a single reamer, headspace gauge or any other tooling. Scissors and shim stock just lets a guy avoid buying 2 gauges. I can't help it if you are too Neanderthal to grasp this. I've seen way too many pieces of brass that were not close enough to set headspace with. But of course you are the world's finest gunsmith, rifleman, marksman and goldfish killer...
Done with this. I hate mud wrestling with a pig
As long as a guy is setting a rifle up for self and building ammo to fit that chamber, it is of little import if that headspace matches SAAMI specs or not.
Ex: Savage in 22-250 with bolt set back enough to accept no-go gauge. Early days, I did not know I could easily adjust headspace on the rifle.
Instead I ran a 243 expander through all of my brass, the necked it down just enough to chamber with positive headspace. I put about 1000 rounds through it that way.
Would a guy do so for a paying customet? Of course not.
Would I sell that rifle? Not on your life! Not even to an enemy.
It was later rechambered to the aforementioned 22-243AI.
