John: Yes (assuming you have everything else in your ballistics worked out).
Word of advice - if you use 4000NV, after you input all atmospherical data into the software, you might want to leave Kestrel's screen on DALT (density altitude) and occasionally verify it (change in DALT will give you indication of sudden atmospherical change - it can be rapidly changing baro pressure, temperature rise/drop, etc.). And even that is not always visible - you may get the same DALT reading when humidity change offsets slight baro pressure change, etc. and one might not notice that the ballistic solution should be re-calculated. And you probably already know that for real surgical ELR precision there's a ton of other variables as well, all the way from barrel temperature to the actual temperature of the round you are chambering, etc., but most of these cause minimal differences that one often cannot correct with coarse/tactical 0.1 mil clicks.
However, in my experience the most common cause of misses in ELR is error in wind estimation, and spindrift and coriolis effect (better said - lack of compensating for them) is usually attributed to this as well.
Bottom line - to finally shut my mouth since I'm probably preaching to the choir, ELR is about perfection, but even if you do have perfectly worked out ballistics (banding/trueing and compensating for all variables), you have perfect shooting/trigger execution, you are using perfect rifle and perfectly reloaded ammo, etc. there is still a small portion of 'shooter's luck' involved. We can get very close, but math/physics/sensors/technology/doppler and actual empirical data etc. all only go so far, and until we'll all switch to laser-guided bullets (or at least will have access to cheap multiple-laser-atmo-scanning devices able to monitor and 'predict' the wind conditions along the complete bullet flight), until then we'll never be able to compute ballistic solution that would work 100% time, and perhaps not even then...
Sorry for my long post again, good luck and shoot safe

Yes your Right, I do ok behind the trigger But these Apps are driving me crazy because I am getting 3 differant solutions
and only one matches my range finder the Strelok free version and the Strelok+ matches my LRF but this new Strelok Pro does not and its numbers are a bit on the wild side
Strelok+ Says @ 2000yds= 408.8fps, 55.7ftlbs, and a drop of4262.08"inches, ( @ 881yds = 27.1 moa )
Strelok Pro says @2000yds= 818.5fps, 223ftlbs and a drop of 2973.23" inches, ( @ 881yds = 26.29 moa )
And my Bushnell G-Force 1300 ARC says ( @ 881yds = 27.1 moa )
This is based on a .270 150gr, BC of .480 at 2828, @ 29.92inhg, 59deg F, AT 0 Alt as per sighting in weather
so something is seriously wrong somewhere??? and I just cant figure it out so I think what I will do is use the Plus version and Add or Subtract from the final Solutions as you said because your formula is right its just my App that is Letting the side down.
Thanks Mate,
John
