I'm looking at putting together a collection of bushings to ride inside the bore. I want to use these to indicate off of when dialing in the muzzle or a barrel that has been chambered in something smaller.
What sizes would I need for the common cals?
6mm = .2345" + .2350"
257 =
6.5mm =
7mm =
30 = .2995" + .3000"
338 =
358 = .3495" + .350"
Help me fill in the blanks or correct the info I have if it is wrong.
