[QUOTE="westcliffe01, post: 788230, member: 35183"] If I take a 308 as an example, shooting 150gr SST factory ammo, at 600 yards one is holding 12 min of elevation (assuming a 200 zero) and 5mph cross wind would need a 3 minute wind holdover. The Nikon SpotOn software does not show where 3 minutes is on the horizontal axis and there is only one reference mark anyway which is there the thick bar ends and the thin one starts. It looks like 600 yards is part way between the last BDC circle and the start of the thick post. Anyway, trying to interpolate a SFP scope reticle subtention is beyond my mental capabilities when I'm in the field under pressure... tried it, missed a lot, now I connecting better with my FFP for those sorts of situations.
