Re: Ballistics data help needed
Odds are that cartridge was tested in a universal chamber and a 24" barrel. Your velocity may be higher. If it is then it will probably only be 50-60fps higher. But, other factors can determine velocity. I would shoot it over a chronograph if one is available. Your other option is to put up a large target and shoot at it until you have dialed your rifle in for that particular load at all distances that you will shoot. You can write down your dope and use it for future engagements. Just make sure b4 you go to the trouble that your zero is set for that round and you don't change it afterwards. A 1" difference in zero at 100yds can make a huge difference at 700,800,900, etc.
