Well my first question is where are you finding the one piece pic rail?
My second question is have you considered how much the one piece pic rail is going to cover the action? I am running a Warne two piece mount with QD rings and two different scopes. If I were getting into some fast and furious shooting, I would be taking the scope off to facilitate faster reloading.
I KNOW I'M NOT A PH. That acknowledgement should keep a few quiet and prevent some spilled libations. I ALSO BELIEVE THAT RELYING ON THE PH TO SAVE YOU IS THE MARK OF A FOOL. Whoops! There went the libations.
Back to my point, I am almost ready to have the mounts machined to get rid of any unnecessary overhang on the action. That's how serious I am about being able to reload this rifle quickly. I am not particularly special or gifted, but I have long arms and I can shoot my rifle very rapidly for as big/long of a cartridge as it holds. The magazine is not very big at 3+1. A six round magazine would really be a nice touch.
