[QUOTE="MontanaRifleman, post: 280267, member: 11717"] Bryan, Thanks again for your reply. If I use absolute altitude I wont check standard or corrected, nor input my elevation as I understand it. I'm still trying to chew and digest this G7 drag profile and It might take a little while. In the interim I'll use the the G1 and try to guesstimate the averge as best as I can. While I have your attention, I thought I would run something else by you. Last year Walt replied to an email I sent him saying the VLDs minimum expanding velocity was about 1825 fps. Nosler advertises Accubonds to ba about the same. Interestingly, whne I read some of the threads and posts here, it seems the AB's will open at velocoities 200-300 fps lower at LR. If this is true, I wonder if the jackets and maybe the lead core might soften a little due to heat friction from high velocites and longer TOF? I know your more into the external balistics rather than the terminal ballistics, but I wonder if you had any thoughts on that? If the opportunity presents itself, I may try experimenting on antelope. From my own perspective, if the VLD open at lower velocities down range, it would extend it's hunting value to me.
