Getting ready to do my first barrel swap on a brand new Tikka. I'd like to keep the factory barrel in pristine condition so I can offer it up in the exchange. I have a big shop full of equipment (but no barrel vise) and I was thinking that I could pair a couple aluminum blocks in the mill and then bore down between them so I have a radius in each. I've got some rubber or leather I could line them with and then squeeze the setup in my shop press to hold the barrel. Seems reasonable to me; anyone else done this?
