I just found a Leupold LINK explaining different reticles; the SPR starts at page 23, with pics of the reticle starting on page 26, with table 9 showing the holdovers, and table 10 and 11 showing how one uses the SPR reticle for quick ranging. The ranging seems slick but I may be easily amused. As far as the holdovers, it could be more precise obviously but it doesn't seem totally impracticable.
thanks for the swfa tip
