Maybe I'm missing something, but a different thread got me thinking about this. I don't do for any other calibers, but for .223 & 300BLK - since 95% of mine is going thru an AR - I load to mag length just about - 2.255" generally. Unless the data does call for mag length like a 77gr....
If bullet has a cannelure, then I load to the max length possible and still hit the cannelure.
Is there any reason to NOT do that and follow the often much shorter lengths in load data? I don't think you can come close to hitting the lands with anything in .223 loaded for AR mag length - at least not for any of my dozen + ARs & couple of bolt guns in .223.
