A cheep bunny basher is a 22 bolt or semi-auto rimmy, @ £40 per 500 shots, not much use at over 50yds to be honest, they will shoot more distance but the kill impact is useless, over 100yds.
Vermin control best is the 22 Hornet, for 25-200yds, a heavier head than the 17 @ 30-45gr you can bash anything, bunny, fox , cheep to reload & a suoerb round.
fox & small deer 223, good to 300yds+ accurate , relativly cheep to load.
when applying put at least 5 guns down, it makes them feel good about taking one off ya, so 4 will suffice,,
