over the past few weeks ive been trying out two different types of 22 ammo,aquila super x subs,and winchester super x subs...the aquila tight groups at 50 yds, also in the field clean kills at 83 yds, but i think that the winchester is harder hitting, a clean kill through the shoulder at 125 yds. {aquila £1-90 a box winchester £3-70 a box.}
