I have a M1A SA Standard. I mounted a Sadlak aluminum mount per the instructions. I have Blackhawk tactical rings 1 inch high I believe with a scope from Cabelas, for now until I can decide which other scope to get. Anyway, the I can't zero the scope. What it's doing is shooting way to high, I lowered the elevation as far as it can go on the scope and shoots damn near 12 inches high. I finally got it on paper at 50 and shot nice groups, but at the top of the paper and this was with holding the reticle center mass. Same thing on the 100 yd line. Any and I mean any help would be appreciated it. And for the record I had a Marine Sniper that used to be with FAST spotting for me and even with both our heads together couldn't come to a conclusion. I spent a hell of a lot of money today in ammo.
