Ballistics Tables or Balistics Programs

[lgray88 4]

anyone know of ballistics tables where the zero is set at 100 yards becuase all the versions ive seen are all 200 yards which isnt much use to me as my rifle is set too 100 yards, i just wanted to have alook out of curiosity to see if what the bullet does on the tables is true out in the field.

this is pretty advanced for me all these abbreviations , LOS angle is this line of sight angle can i just leave this and the cant angle at zero? does the ballistics calculator not require anymore information to carry out its calculations??

Yes, leave set at zero, this angle change will give the true distance to the target, above or below horizontal reduces the true distance,(corrected for gravity) type in your bullet weight, coefficient, available from the manufacturers web site, the muzzle velocity, my .308 hits about 2700fps with 155's, experiment with the wind speed, target speed should be zero.

Have fun,

go to stevespages on the net and download the lee shooter program, it's very easy to use and accurate..............

just after seeing you don't have a chrono So your wasting your time as your bullet drop will not be accurate.........

the loads in the reloading books are shot under factory conditions and with a standard length barrel which will be printed at the start of the calibre you are reloading for............ you could be as much as 300 fps down on the factory quote.

Here's a good online ballistics program

Fill in the details as best you can for instance a 223 bullet will have a balistic coefficient of 242. weight of say 55g and muzzel velocity of abot 3200

Think thats right????
