cold shot adjustable scope base..

[300 whby]

Hi gents, Anybody on the forum had any experience with the above mentioned base, I'm currently building a 338 Edge & the scope I have is a Nightforce 8-32X56 NSX which only has 65 MOA adjustment,I 'm running a 30 MOA rail but it's still not enough.. I have plans for Nightforce ATACR ( 100 MOA)which will get me to 2 K, (90 MOA) but the budget does'nt run to that at the moment..
This looks like a good idea, BUT any play in the hinge would be a problem, i guess you could dial your base up to approx MOA then check your zero for that elevation then fine tune with the scope adjustments..
Any thoughts ???
