[QUOTE="dfanonymous, post: 1980445, member: 97050"] It’s not necessarily that your chrono is wrong but one or many of these are off as they are the ONLY things that will effect your dope to 500. Scope tracking range estimation errors temp/pressure altitude error BC error and last but not least, velocity error. The issue is for a 7mm rem mag you are still just outside of max pbr distance lol. If you’re using a box BC then it’s not going to be so off that it’s going to throw your solution off .8 moa @ 500. It’s not the ballistic apps as I’m sure people use them just fine. None of your verticals drifts will have affect at such close range. Chances are that it’s one of the usual and basic things listed above. Variation in software is not truing it, or understanding it. I have no ballistic profile that is outside of reality. Some of these cartridges out to 2 miles as far as drop is concerned. [/QUOTE]
