[QUOTE="HoytemanPA, post: 110509, member: 286"] JonA, Drops are nearly interchangeable in my application. "My" BC for 220SMK is .601 and 210SMK is .590. Looks like 210 gives up 60lb energy and an inch in a 10wind at the speeds I ended up with. They shoot slightly better in my rifle. For reference I figure a .551 for a 200gr Accubond. I can't relate this to any calculated BC, not changed based on speed but rather a single value that I use to shoot stuff from 100 to 1300 yards using a program that calculates very similar to Exbal.
