Sinman, I guess you missed the part of my reply that said "MY fully resized .221 FB brass will indeed fit into the .223 AXIS chamber and headspace on the shoulder. Again, using a COL tool, which I use on all my rifles.
Now please explain why I would ream the chamber larger than necessary.....
I neck size (only) all of my varmint rifles, for a nice snug fit in the chambers and haven't had one issue in nearly 45 years of reloading dozens of bottleneck cartridges. Checking the dimensions of both cartridges with a good digital caliper, I can only see .002" less body taper on MY .221 FB cartridges......
Even Brownells and Midway sell 'rebarreling kits' for Savages which consist of: a bbl, a wrench, and go and nogo gauges.
Please elaborate how reaming larger than necessary would be 'better'. I just don't understand that logic......
