[QUOTE="Fiftydriver, post: 116722, member: 10"] Mike, THat will give you a hell of a start of developing and tweaking your drop chart to match your actual bullet trajectory. As the fall temps roll in you will need to do a bit more tweaking but this test will get you alot of information quickly. I generally do not shoot every 100 yards out to 1000 yards. Its fine if you do but in my opinion not needed. To accurately plot your bullet drop I like five pieces of data: -Scope to bore height -Muzzle velocity -200 yard impact height -600 yard impact height -1000 yard impact height If you have those numbers and your ballistic program can be tweaked to match or come VERY close to all the drop numbers in your shooting area, you will have a very accurate drop chart. Two down range impacts can work but three is vastly superior as far as accurately predicting your bullet drop inbetween those known ranges. Again, more ranges does offer more data but if your drop chart matches up to three different down range numbers then it will more then likely match up with everything else inbetween as well. Just my opinion. I do things quite simply. Perhaps to simple for some but it does work. Let us know what results you get!! Kirby Allen(50) [/QUOTE]
