Since the 3-18 has 22 MILS of travel (80"), which is 11 mils (40") up and 11 mils down (40") down. Adding a 23 moa base you would have 17.4 mils (63") up and 4.6 mils (17") down.
Will 63" get you to 1k? Yes, but not really well with a 168 gr bullet, which will go sub-sonic just north of 900 yds.

While the numbers (math) are logical, this is theoretical. In practice, on a flat-top, I expect you to have much less than 63moa of up travel. You won't start out zeroing at 100 yards with the reticle centered. Bottom line - it will be close...
