Ok I'm sure it's been covered somewhere but finding it is a different story.
When changing barrels do you need to use a go and a nogo gauge.
Or just tighten until tight ?
Additional info, barrels supplied and chambered by gunsmith
Thanks

Mozzie,
Just tightenup. You saw me do it in Townsville at the July shoot.
