    Isn't there a calculator or chart somewhere that will give you fps, drop in yardage and energy of bullet if you put in the bullet dia and weight you want to shoot?

    Most reloading manuals lists these charts along with the technical data in the back of the manual.

    Sierra infinity 6 is a CD put out by the folks at sierra. You HAVE to really know the velocity, not what the book says it SHOULD be. That means you need a chronograph, or know someone with one to clock tour bullets.

    Diameter has nothing to do with trajectory, bullet shape is what determine drop at long distances. Also, the bullet you have must be on the CD, most match bullets are on there.

    Since you didn't specify whether you're asking about handgun, rifles, shotguns or slingshots, that's my answer.:rolleyes:

    You are looking for ballistic calculator. Check the link for details.

    Finding muzzle speed and chamber pressure from round and barrel parameters is studied by internal ballistics. QuickLoad solves the internal ballistics problem. I do not know any online programs that do the internal ballistics.

    Finding drop, energy and wind deflection of the bullet by muzzle fps, bullet characteristics, and data on wind and atmosphere is external ballistics problem. There are many online calculators for this. Here is one. QuickTarget program, which is made by the same company as QuickLoad, solves the external ballistics problem. It may take data from the QuickLoad, and in addition to numerical answers draws a lot of useful graphs.

    Last year Federal sent out a notice that they have free ballistic software on their web site.
    I haven't used it, so I can't verify anything about it.

    Winchester also has one on their website.

    Hope this helps.

    Free software from Remington too. I've used it for years.


    The trouble with a lot of the ballistics programs on-line is, you have to know the Ballistics Coefficient of the bullet in question before you can use them.

    The freebies from the ammo companies already have put that in the calculator so you don't have to know anything about the bullets BC number.

    So easy, even a cave man could do it!
