Looking for a one piece, affordable base for my SA, model 11. I would like to eventually turn this hunting rifle into a long range in 243 and wondering if a 20 MOA base will be odd to hunt with? Would the typical 1" scope have enough travel for a 200yd zero?

Why I am asking is my current scope needs to come a little rearward for quick scope acquisition, and the current standard rings and 2 piece bases hit the back side of the front bell of the scope, keeping it from coming back far enough to suit me.

I am thinking also of rings that extend back a little also. The MOA base would be a good thing for later on.
