Who makes a good .22 Cal octagon barrel these days? I'm thinking of making up a low wall in Hornet. I've searched the web and not much comes up. I bought a green mountain, but my metal smith doesn't care for the dimensions. The barrel shank is round and will only give .020" or so engagement on the face of the action outboard of the threads. I fully agree that this doesn't sound like enough. I'm thinking of something like a #3 Win weight. It will be transitioned to round with a wedding band.
