I pulled the trigger and placed an order for new barrel chambered in 6mm AI. But I am having a hard time finding headspace gauges for this chamber. Does anyone have a suggestion as to where I should look or would anyone have a set they would be willing to let me borrow? I would pay you back for any postage fees. Also, if anyone has been shooting one of these and wants to share any load data it would be appreciated! I have been looking at shooting the 75gr vmax since my barrel will be a 1:12 twist! Thanks for any and all help!
