Yes, it uses the same gauges as the 243 Winchester, 260 Remington, 7mm-08 Remington, 308 Winchester and 358 Winchester
Set it so it closes on a go and won't close on a no go if you want a sloppy factory spec headspace.
Of course you can build a safe and potentially more accurate shooter that will stretch your new brass less, without the use of any gauges, but that is a whole new can of worms. ;D
