air rifle info

can anyone tell me how far a pellet will travel when shot from a .22 air rifle with 12ft lb power

[Peter Pedant]

and what is the angle and so on.
I think all they want is a simple calc

12 ft-lb is an energy by the way, so that is the energy that is given to the pellet. for ce timmes dist traavelled

So how much in lb does a pellet weigh ?
tenth or hundreth of an ounce ?

and the distance travelled is d

so 12 must equal d times the .01/16

so d is 12 x 16 x 100, iew 19200

o god I hate imperial measure, which is about 6500 yards or 3 miles

Hmm I htink I underestimated the weight of the pellet

Anyway I think the calculation is on those lines

must be about ouch

Basically all i want is a rough idea, the reason being if i miss my target how far will the pellet travel befor it drops. i realise the weight of the pellet etc is going to have a bearing on this but i dont know what they weigh yet but i will find out.
i just want to be sure that if i miss my target i dont hit something i shouldnt half a mile away or how ever far the pellet will travel.

Hi again,
as far as i am aware the pellet weighs about 0.94g
hope this helps

Cut down answer because this site is playing up again

http://www.pyramydair.com/site/articles/formul as/

pellet =14.5 grains

muzzle velocity 600 fps.

Target 1metre off of the ground = .44 seconds to fall 1metre ( sqrt(x/5) where x is the number of metres high)

So it will travel 264 feet

ctd.

However air resistance will slow the pellet so it's travelling slower than 600fps when it passes the target

This relates to firearms

The 0.22 weapons lose about a 1/4 velocity at 100 yards, heavier too I'd guess you'd lose over half the velocity at that sort of distance say 100 feet

I hope this helps a bit but a lot depends on the specifics

I have a .22 Air rifle at 12ft lbs -its effective killing range is about 50 yds and maximum range is about 200 yds with the wind behind it

Thanks woodchopper,
thats the kind of answer i was looking for. a simple guide in plain english.
THANKS EVERYONE FOR YOUR REPLIES.
