5 lbs jack rabbits

[hellzbellz]

i live in alberta canada, i have a few questions, 

is 18 FPE good for rabbits

I'm shooting 750 fps with gamo magnums 15.43 grain
how far can i shoot with my setup before my pellet loses speed
and energy

 

[gorgata]

download chair gun ballistics program and input the data there is an options for energy retention at yard intervals

it will give you a nice chart with pretty much all the data you want

You only need 7 fpe on impact to kill a rabbit, with head shot.

I put it in Chair Gun and it looks to me like you'd be good out to 50yds. As long as you can do your part and put the pellet where it needs to be.
