My understanding is all varmint barrels are 22mm at the muzzle. (.8755 inch or something) It would be the same for all varmint barrels. I can’t imagine it would be different from my 6.5x55 Swede to a Creedmoor. I’ll double check in a couple days when I get home.

Can confirm the varmint stainless barrel in 6.5x55 Swede is 22mm/.870”

I ussually shoot with a couple guys who shoot 22250 and 6.5 varmints, so i was going to check, but didn't make it out this weekend, so I can't confirm those calibers. I checked my 223, and it is 22mm
