Thread: What's the Deal?

What zero range for the rifle? And what zero range entered in the app? Because I'm waiting for a plane in Singapore and have had 3 very large black coffees I have had a play with JBM.

With 2644fps and 100m actual rifle zero/100m zero entered in program the 500m elevation is 3.8mil, 650m is 5.9mil (ie the ~corrections that you required to hit)

With 2644fps and 100m actual rifle zero/200m zero entered in program the 500m elevation is 3.1mil, 650m is 5.2mil (ie the 500m ~correction that did not hit, we had no information supplied about misses at 650m)

2500fps is super slow for that powder/charge/bullet/case.

A theory: your rifle is zeroed at 100 meters but the program was set for a 200 meter zero. I can believe an easily overlooked data input error, they happen regularly.


Edit: I think I accidentally did all that with JBM set to G6 not G7 but that just kinda proves my point of how easy it is to miss one little input in a program, doubly so outdoors on a phone etc
