anyone around the Cotton County area have a set of go/no-go gauges for 6.5 grendel? Or way to check without the gauges? Thanks
Depends on the gun, cartridge and chamber.
For a fast stepping varmint or big game cartridge that heats a barrel up in just a few rounds, .0035 headspace should keep the action from locking up when it gets hot from extended shooting sessions...
With my favorite long range rifle that is NOT allowed to get hot from shooting, I have headspace adjusted to .0005. I use nothing but nylon brushes when cleaning the bore, as a single brass bristle in the wrong spot, can cause the action to lock up at the most inopertun time...
How much is too much? I never exceed .004 for any chamber that I cut...
What is wrong with your 722?
