AND...my conclusion was over a long period of time that these so-called ballistic charts are good gizmos to con $$$$$ out of people. Now...some will of course rebut that statement but be that as it may....I'll still cling to my own experience and as stated conclusion! Shoot your rifles with the best load that you can get it to develop....record all data related to weather conditions and then use that data to help you in future shootings! Temperature makes a helluva difference I can tell you that from one day to the next and if not taken into consideration...well...you won't be close to what you're gonna want to hit! Once you've found a load combination that works...don't get caught in the trap of constantly chasing a magic new bullet because there are NO MAGIC BULLETS....just raw physics and well established science!
The latest software is great for plugging in basic parameters, e.g. BC and MV, to get on paper at long distance so that you can confirm your drops.
They're also good for checking the anticipated correction for different conditions such as altitude, wind, or in-between/unknown distances that you haven't shot.
It's always best to verify actual dope in the field.
The ELR guys have to really pay attention to fine details as they get out past 1200 yds or so. ...unless you're just trying to walk it in.
Given the cost of ammo and barrel life, I think good software is well worth the $$.
