It only has G1 and G7. I use G1. I am able to "massage" the BC a bit to make it practically match the drop data from a more airgun specific drag model out to 100 meters. Lately though, for the type of shooting I'm doing (practically all withing 50 meters), the straight up G1 is close enough. I might still do it with a projectile that I really like, but knowing that BC is not even constant (atmospheric pressure), most of the time I don't bother with it.
@MushroomPsyche Thanks for the detailed response. I was looking at rangefinders and a couple other devices with ballistic calculators over the weekend. The included drag models were also G1 and G7 from what I recall. I was wondering if they’d work for airguns. I also saw that some products have option to enter custom profiles but I am clueless as to how any of this works. It’s pretty much all new to me, although I’ve been reading about this stuff on the forums for close to the last couple of years trying to grasp some sort of understating.
What I did was generate a drop table for both G1 and I believe I used GA at the time from Strelok Pro. I then compared the two tables. I then massage the BC on the G1 table to make a good fit compared to the GA. Mind you, it's not perfect but everything is usually within a click or two on the mil turret to the 100 meters range I looked at.
@MushroomPsyche GA is a profile that I recall reading is better suited for airgunners. I just don’t recall all of the details.
