How about starting out with 4,000 ft pounds of energy out of the barrel and heading down range?
3 "bangs" in one shot....
recoil.... report.... K-THUD down range!

or

150 grains doing 2800fps or better?
That way youkeep measuring elevation drop in inches instead of feet.

30-30's might be okay fer deer in the bramble patch but kinda whimpy for out west where horizons run long.
