I have recently acquired a savage 110 preaccutrigger with the flat rear in 30-06. I have searched high and low for a 20 moa pict. base (as I will most likely convert it to a 300 win mag) without much luck. My preference is steel, but will take an aluminum base if I have to. I would prefer one with a recoil shoulder given the upcoming conversion. Warne has a 20 moa steel base, but I can't seem to find one in stock. Not sure if it has the recoil shoulder or not, but it appears to be pretty much what I am looking for. Are there any other bases for flat rear magnums close to what I am looking for?
