Re: What blast for stainless barreled action?
Bead blast will polish, giving it a luminous look. Oxide, lets say 120 grit will give it that dull matte finish.
Bead blasting will hold up much better against scuffs and scratches showing, where oxide finish will show everything.
If you decide to go oxide for the matte finish, you can oil the barreled action down really good directly after blasting. This will help it from not being so prone to scuffs showing up, plus it really softens the look.
