With the .270, you can sight it in 3" high at 100 yds and run 140's with a G1 b.c. of .650 at 3000 fps or 150's with a G1 of .710 at 2800 fps in an 8 twist barrel or if you still have a 10 twist barrel because you haven't shot it out yet, run 140's with a b.c. of .528 or .508 or 150's at .541 at the above speeds with temperature stable powders. Don't need a 20-22 oz scope that dials if you're only shooting up to about 350 yards, which is about as far as the majority of hunters can actually shoot accurately, and about as far as most game presents itself, just use an 11 or 12 oz scope. Don't have to hope the animals stay still long enough for you to measure the distance and then look up how much you should twist your turrets and then twist the turrets...just point and shoot (hold a little high at 350 yards). If you do want to shoot your .270 further than about 350 yds you can put on a 20-22 oz scope and twist the dials or use hash marks on an 11-12 oz scope.
