HI ,iuse the 17 hmr good little gun ,try using the 20 grain bullet instead of the 17 gn .
if u set the 17 up with a good scope ,head shots from 50 t 150 yrds no problem.
the 17 is badly afected by the wind, the noise level is loud even when fitted with silencer, the ammo is expencive, apart from this its a great alround weapon.
GOOD HUNTING
