[QUOTE="Jeff In TX, post: 35272, member: 1522"] Birdshooter, JBM's online program is fantastic, not to mention it is free. I use the RSI Shooting lab, which is the most powerful program on the market and has many more capabilities of what the JBM on line program currently offers. Don't get me wrong; I really like the JBM online program and used his 90’s version JBM OT pc program until he stop selling and supporting it. One of the RSI program features that I really use is the Estimate Drag Function. This feature allows you to take your actual range data and directly compare it to all of the different drag models. This way you can pick the best drag model that fits your bullet/load and actual range data. Then you don't have to guess if you should use a GL, G1, G5, G6 or G7 drag model. Hope it helps. [/QUOTE]
