working out FT LBS TO FPS

[gtfreight]

ok thanks

but how do i find the Muzzle velocity
on a air rifle ?

thanks

If you don't know the muzzle velocity you can't work out the kinetic energy in ft/lbs.
I don't understand why you give a fps reading for conversion, then you ask how to find out how to get fps.
You can buy inexpensive chrono's (Combro) for about £40 that attach to the end of your muzzle and they will give you a read out in fps. They can also convert this into ft/lbs if you know the weight of your pellet.
