Thanks GD.
I don't know what the Tikka/Sako barrels are, but I would love to be able to swap barrels on the old A-Bolt. It is actually wearing a fresh barrel on it now. A buddy's dad had a new .270 Browning with the Boss brake on it, but wanted a 25-06. I ended up with his barrel and had it put on mine. The thing shoots amazingly well, but for kicks I measured it one day and if I recall correctly there is only about 19"s of barrel before the muzzle break.
I was thinking about consolidating cartridges anyways, so if I could make it a 30-06 or .308, using one of the barrels I already have, then that would be great. I just don't know if Browning and Tikkas are compatible (or Remington).
