[QUOTE="bassassassin104, post: 2627150, member: 28244"] IMHO, as long as your tune is decent you are correct. Mikecr said it pretty well and I agree with him. A ladder test will show you how much velocity variation your load can take without seeing extreme variation in point of impact. As for the direct affect of velocity on bullet drop, you can play with a ballistics calculator a bit and get a good idea of how much variation to expect with a specific ES. For example my .260 from 2920-2950 fps shooting a Bullet with .625 BC will have a theoretical vertical variation of .6” at 400 yards. That calculation is assuming everything else is exactly the same every time but it gives you a decent general idea. [/QUOTE]
