***Update on the attached file- added 1 & 2 oz then added weight in grams to the oz listings for the varous columes

I finially joined the Form and decided to add my 2-bits to the subject

I've attached a Zipped PDF file that I think does a fairly good job at helping one to see just what a Sling is capable of doing along side say...a standard pistol cartridge. I beleave that this should represent standard store bought loads.

Just a little background on the Calculations used

Km/h = 1.6*MPH

ft/sec = MPH*5280/60^2(60 squared)

5280 ft per mile

m/sec = km/h*1000/60^2(60 squared)

1000 meters per km

60^2(squared) gets the calulations down to the second

Amount of Kinetic Energy = Weight of the projectile*Velocity in ft/sec^2(squared)/Constant

Constant = 32.163^2(squared)*1

Acceleration of Gravity = 32.163 ft/sec

Normally in the constant you will see instead of the number "1" for 1 pound, you will see the number "7000" because there are 7000 grains to the pound & bullet weight is in grains. Since that seems to be way too small of an increment of measurement for Sling Projectiles, I just left it at 1 pound.

I'm looking for ways to improve this, or add to it, or correct any mistakes

I hope this is of use to you
