26" long is plenty for the 300 Win Mag or 300 WSM. If you can live with a barrel as long as 26", I wouldn't go any longer. I went 25.5" just to be different.
If you handload, no functional difference between a belted vs non-belted cartridge. If you go 300 Win Mag, either neck size or size the shoulder back so it barely (0.001") cleared the shoulder in your chamber. In other words, after the first shot with unfired brass, all the rest of your cartridges should be headspaced off of the shoulder rather than the belt, if you want to maximize casing life. Hope this makes sense.
