All very good stuff. For you guys with more experience. Do you find that you get accurate shooting solutions from these devices each and every time you use them? My concern is that I live in the Midwest at 1400' and where I hunt is between 5400' and 8900'. If I know that my system works perfectly at 1400 feet and I take it a thousand miles west and a couple thousand feet higher and the barometer has changed and the air density is different are the calculation that are made by these devices accurate?
I have high confidence with the Gunwerks G7. It has produced accurate drops over a several year period at various locations with widely different atmospheric conditions. My locations range from 350Ft to 5000ft with temperatures from 10F to 80F. While I haven't put the Sig2400 through s full season yet but it looks promising. An important factor is to make sure that the temperature effects on your powder(effecting velocity)is either understood and corrected, or a temperature insensitive powder is used. The Hogdon Extreme powders have worked very well for me with minimal effects from temperature variations.
