Check my math, but I *think* 3oz is a quarter pound (12/3=4, where as 4oz would be 1/3 a pound

how many pounds of force does a normal paintball have going at 300fps. All the math is confusing me and i like math


do u mean grams not grains? and where did u get 450240 from. I'm not disagreeing with u or anything just trying to understand this so when people tell me that paintball can kill u or hurt u bad(its been done, some people have no common sense) i have proof to tell them that it cant

Thats 90 grams if you want to stay with Manikes conversions to metric. It's noticable when you hold the two side by side but after all its just three ounces...

lol, that's almost a "qp".

A normal paintball weighs from 50-54 grains approximately. So at 300fps a 52 grain paintball would have 10.4ft/lbs of energy.

I mean grains. It's a unit of measurement commonly used to measure bullets etc over here. It's how I used to measure air rifle ammo, and the same scales are what I used to weight paintballs back in the day.

450240 is the 'fudge factor' which brings all the units to the correct level such that you don't have to mess around with lots of decimal places or conversions when inputting the measured values. It makes the formula very easy to use.

At under 12ft/lbs a paintball can't theoretically directly kill you. (it could indirectly by causing an embolism or something? ) but at over 12ft/lbs it does theoretically become possible.

This is why chronographing your guns is important.
