I've been tossing around 6.5mm,7mm,.338 and .375 Well out of them all I'm leaning towards the .375 It's available in good weights with decent BC's. Now I've also been trying to decide what case to use for this project. I thought about a cut off .308 a necked down 450b and of course a necked up 25WSSM. I'm leaning towards the WSSM due to the powder capacity. so what ya think about a .375WSSM ar15? I would probably have Dtech build it for me.
