sooooo.... now that I have my double I’m in need a little help on a starting point. The Rizzini is 9.3x74r and regulated for S&B 285 grain ammo. I shot it the other day and it shoots beautifully but.... I’d like to load tsx’s or Swift A frames and try to get it to shoot equally as well with those. Anyone have a starting point. I’m probably over goat thinking this one but before I waste a bunch of time and money I’d like some advice from y’all that are experienced loading for doubles.
