You can make 2725-2750 with a 24.5" barrel and a 300gr bullet. I have one at the moment. I've also had 18.5", 20", 22.5", and 27" Lapuas. The 24" is the best of everything. I despise long barrels, so I'm a bit biased, though. if running suppressed, a 20" makes a damn nice package.
With that said, I'd probably go with the Norma if I was starting from scratch and had your plans in mind.
