I’m looking for something basic to graph trajectory of various factory loads, calibers, optics heights etc. Key features I’d like to have is the ability to set different sight/optics offset, zero distance, and graph several simulations at once for comparison. I don’t need anything too complex since I’m not reloading or trying to simulate groups at 1000+ yards but would like the ability to input some of the environmental conditions. Freeware is good but I’m not opposed to paying for something that is more user-friendly or has some features you would recommend. What do you’ll use and why? I appreciate your guidance in advance...oh wise forum members!
