[QUOTE="Ring, post: 707761, member: 2952"] "Truing" your ballistic software “Lowlight” You can calibrate most software and is simple enough too do. Some of the elements in the video “Magpul” are correct for other software, like actually shooting to a range that puts the round around 1300fps. (example) The steps are simple enough, calibrate your scope and if necessary adjust the software using the sight offset, click value, etc. This will work with most software to include the iPhone Apps. Then, calculate actual drop. You can start at 300 yards to begin. At this range you can adjust your BC if necessary. The BC will move based on the rifle shooting it. For example BulletFlight has an option in the utilities area to adjust BC based on Drop. it will give you a new G1 or G7 which you can then input into your data section. Lastly you can calibrate the drop out to 800 yards like the video. Checking at distance is the final step, but you should have at least choreographed your load to start with, if you haven't then some software does have functions to adjust it based on drop. Certain software has a DK function to bend the curve, this is used in place of adjusting the BC or MV, so you can do it a number of ways with a number of different software solutions, not just the Horus. Remember he was hired by Horus in the beginning to work and sell Horus methods and products, so of course they are not going to inform you of other methods. Calibrating the system like above I have taken software like Field Firing Solutions and Patagonia LB3 out to distances beyond 2000 yards with very successful hit rates. Inside 1500m the first round hits where more consistent than when you didn't do it, and at 1000 yards and in it was too easy with a rifle like a 338LM. The system calibration should be: 1. Muzzle Velocity using a chronograph 2. Scope calibration to at least 48" 3. Drop to 300 yards to tune with then 4. Drop to to 800 yards to fine tune. [/QUOTE]
