[QUOTE="Bravo 4, post: 1629142, member: 8873"] I didn’t read all the replies, but my $.02 is an add on to the post I quoted: even with a chronograph you should shoot distance to verify your drop (and true your data). There are other factors, such as turret adjustment precision and such (I would test that as well). Use the given BC and if available some chrony data to get you started on your drops, then shoot various ranges and adjust/fudge those input numbers accordingly. If no chrony then SWAG the velocity and go shoot, the drop data will help with that. This isn’t anything new, Leupold has made a CDS (BDC) turret since the 80’s (well before my time with them). They had them on our 10X M3 Ultra/MK4 scopes on the M24 Sniper Weapon System (and somewhat one with the 3.5-10 on our M110). There are ways of using it even when it’s “off” or when conditions change.
