Im not sure where you are getting your drop at 500 from....but I think you might want to check it again...should be closer to 36+ inchesThanks guys for the info. Reason I was asking is I have a 7mm stw and the table I'm using says a 12.5in drop at 500yds.if your sighted in at 200 yds. in my old and feeble mind that's turning turret about 25 or so clicks. Not sure if this is correct or not.
