No problem, in fact the leupold base will allow you to use those two rear beveled screws for the rought windage ajustment.
I have seen some scopes run out of windage adjustment because the screw holes in the receiver were not drilled center to the barrel, we are talking thousands of an inch here.
I use a bore sight to mount my scopes, and they will be on target for the first shot, if the screw holes are centered. By on target, I mean it is hitting the target where I can finish the fine adjustments.
Get the scope mounted with all screws tighen and loctite on the base screws and scope ring screws. Try to center those two beveled screws as best as you can.
If you do not have a bore sight, go to the range and sight your first shots in at 25 yards. You want the elevation to be dead on at this range. If your windage is off to the left or right, you use the rear scope base screws to move the bullet strike to the left or right as needed. Lets say you adjusted the elevation to dead center by moving the cross hair adjustment down five clicks, but the bullet is hitting to the right about 4 inches at 25 yards. This will put it off 16 inches at 100 yards and means you must use 64 clicks left windage by using the scope adjustment. Instead of doing this, your scope may not have that much adjustment. loosen the left beveled base screw about 1/2 turn, and tighten the right beveled screw 1/2 turn and the next bullet impact should strike closer to your aiming point. Do this several times until you are hitting the aiming point dead center, then finishing up by going to the 100 yard target. I am starting you out at 25 yards in case your scope is mounted far enought off that it will shoot to the side of the target at 100 yards. Hard to make your adjustments if you do not know where the bullet is hitting.
There is another method that you can use to sight your gun in with only one shot, but it sometimes requires two persons on a good rifle rest where the gun will not move while you make the adjustments. The one I gave you is very simple way to sight the rifle in. When you think that you have it sighted in, allow the barrel to cool 15-20 minutes, then fire a 3 or 5 shot group to confirm your sight in and to check your rifle for grouping.
The 25 yard sight in should put your bullet impact about 2-3 inches high at 100 yards.
