Re: 1 pc vs. 2 pc bases???
I prefer a 1-piece base on my 300 RUM because it also acts as a brace for the receiver adding strength and making it more robust on a receiver that takes a pounding from such a large magnum cartridge. By making the receiver stronger, it is my understanding that you will see less shock and flex transfered to the optic mount on it.
