I am considering re-barelling a Savage 111. I am using that action because I already have it and it's just sitting around. It is currently chambered in .270 which I have no use for (already have a .280 and 30-06). I can't seem to find a chart with bolt face diameters listed. I would love to do it in .220 Swift (preferably) or .22-.250. Anyone point me in the direction of a chart or list of bolt face diameters? Or even tell me what calibers share the same bolt face as a .270? Thanks.
