Never used to calculate loads, but once i had a load, I liked developing a drop chart and graph, especially comparing loads or calibers. It worked great. This looks like it is what I need. I'll check into it further. Thanks!
I use 2. Each has its plus and minus points. Ballistic Explorer is good but isn’t exactly user friendly. Pretty long learning curve.
2nd and the one I use the most is Sierra Infinity 5. Haven’t checked into Version 6 but hear it’s good. Ver.5 allowed me to graph out drops, windage and velocity for up to 5 different calibers or 5 different loads of the same caliber. Had a very good bullet library from manufacturers built in. I especially liked that I could change the velocity and trajectory table down to 1 yard increments or simple 100-200 yard increments. Infinity has a very short learning curve.
