140 rdf bc

[BLopina]

Went out to 1K today and shot the new 140 RDF. I'm finding the BC to be more about .315G7. It was a very gusty day and that could have affected my results. What are y'all seeing?

had to come up .15 at 800, .2 at 900, and .3 mils at 1K from published BC

I've tested mine out to 1245 yds and the advertised .330 g7 was spot on for me. Conditions were +/- 300 ASL with DA's ranging from -1500 to 2000. Tested in 6.5 Creed @ 2805 fps and in 6.5x47 at 2780.

If you had a stiff left to right wind that could have been a factor, or a flat range with bad mirage could also require some added elevation.

Yea we did have a left to right crosswind. But I have aero jump dialed in on the kestrel and was recording atmospherics. I was testing 2 Charge weights. One with Varget at 2720 in the 6.5x47 and the other H4350 at 2770 in the 47. The 4350 load was impacting lower for some reason. Very bizarre results. Gonna shoot Idaho NRL in 2 weeks. I'll have to test again,

zero is identical for each and was adjusting elevation for each.

Second test shows .315 G7

I got .340 out to 1210 yds. I did have a right to left wind at about 8-10 mph. I'm shooting a 6.5 CM at 2861 fps.
