I have one of the Continental sets and the 30-06 barrels are as accurate (2" at 100yds.) as I could ever expect. I use 165gr Nosler Solid Base bullets but it took about 5 different loadings to find the one that regulated correctly. I also have a .270 Browning "Superposed" double rifle that is scoped. That one is a 3" rifle so far. Haven't found the magic load yet.
