[QUOTE="sscoyote, post: 343898, member: 1133"] That was a great video--probably 1 of the best i've seen--well narrated too, IMO. Like MM said tho the reticle-rangefinding at those ranges is a bit tricky. I looked at the Shepherd catalog and if that's the Model 310 P1 reticle it is designed for an 18" back to brisket deer at all the ranges. If that's true then the "multiplier" in the mil-ranging formula for that particular circle's subtension would be 1000/18 = 55.56. It looks like that's a doe and it appears to occupy maybe 0.75-0.85 of the ranging circle back to brisket but it's hard to tell if the brisket can be easily resolved thru the camcorder. Figuring maybe 16" back to brisket for a doe, then the formula yields--16x55.56/0.8=1111 yds. which aint far off, but if u were +/- just .05 off in the interpolation (almost imperceptible really) that nets a range of 1185-1045. That's 140 yds. difference at that range or +/- 70 yds. Man that's pushing it for reticle-rangefinding. I would also almost say that that flag would help a lot. Would for me at least. Great shot though figuring wind and all!! [/QUOTE]
