I only know the Alaskan versions are hard to find these days and some aren't a fan of the stocks since they attribute bad accuracy to them. I've also heard the walnut stocks on the Africans have split behind the tang under recoil. I've not heard anything or experienced anything negative about the Guide Gun versions.
700xcr,
I saw somewhere else that your 300gr Accubond load is 78.5 gr RE-17. If you don't mind sharing, what is your powder and charge for your 270gr and 350gr loads? I have the same rifle and love it. In the next week I'll be testing some RL-15 and 17 ladders under a bunch of the 270 gr blemished bullets Midway had on clearance a while ago.
The 270gr. load was the factory Hornady. I load 78.5grs. of RL-17 with the Nosler 300gr. Accubonds and 73.0grs. of RL-17 with the Woodleigh 350gr. PP. COAL on both bullets are 3.385". Using Winchester WRLP primers. I use a Lee factory crimp die too.
