[Cheapskate]

wouldn't the sharps round have a lot less drop though?

[OKSooner]

No, the Sharps buffalo rifle fired a big ol' cast lead bullet at a lower velocity with a black powder charge. (Someone help me out with the particulars here.) The .308 (civilian nomenclature) has a muzzle velocity of about 2400-2600 fps, faster than the sharps. Thus it will have less drop at any point of impact.

The old buffalo rounds would drop more because they were slower.(longer flight time,more time for gravity it work)
