ive been looking online to find a site that has ballistic tables for most calibers out to 1000 yards??? most of the charts i find only go to 500 yrds. any info would be great, im looking to compare some calibers for idea's for a re barrel.

thanks

God Lindy you're a saint!! lol You must get tired of answering all these Ballistic! questions.

Re: ballistic tables??

how do you determine your ballistic coefficient and what does that actaully mean?
 
Re: ballistic tables??

See:

http://www.jbmballistics.com/ballistics/calculators/help/traj/traj_exp.shtml

Also note that each entry item has a little blue question mark link next to it, which will bring up an explanation of the entry field.

This is about the minimum data set you must enter for the program to work:

Ballistic coefficient
Bullet weight
Caliber
Muzzle velocity
Sight height above the bore. This is not a critical measurement. Use a rule or tape measure to measure from the center of the bolt to the center of the scope tube.
Zero range

Temperature

Atmospheric pressure - this is the tricky one. See the section on entering atmospheric parameters in this link:

http://www.arcanamavens.com/LBSFiles/Shooting/Downloads/Baro/

Humidity - however, if you checked the box which says, "Standard Atmosphere at Altitude", that box will not matter. That's one of the reasons why it's better to have your own pressure reading, because then you can also enter the humidity and it will calculate that.

Down at the bottom, check the boxes which say:

Elevation correction for zero range
Target relative drops
 
Re: ballistic tables??

Ballistic coefficient is like how aerodynamic the bullet it is. The higher the number the more wind resistance and less bullet drop. The bullet manufacturer will have the BCs on their website. Lindy is a great source of info and the JBM website is will get you started on your tables.
