Still trying to decide 22, or 24 inches. Most likely, 24.
Split the diff at 23".
A couple of years ago I rebarreled three rifles to 6.5CM, .257 Ackley and 7x64. I went 23 inch barrels in all of them just to be a bit different. I like 22 inch and my gunsmith likes 24 inch but was happy to go the 23".
