I had purchased a LH Lawton 7000 SS action (Rem 700 clone) for a new .308 build. The rifle just arrived and I intended to install a set of Burris DD bases and Signature rings which have been sitting here waiting for the rifle. Now that I have taken a closer look at the action I noticed that the receiver has two sets of holes which are spaced the same, I believe .860" ctr to ctr. (unlike a Rem 700), and the holes are larger, 8-40. I contacted Lawton and they said to just put two front bases on the rifle and I shouldn't have a problem. However they also said that I would have to drill the holes out in the bases to accomodate the fatter screws. Can I just open the base holes up and still have enough shoulder left in the base hole for the new screw heads to grab properly? Any other suggestions?
