i agree with whippet, your better off with a shot gun and with the fact pest control might not be good enuff reason to get a fac, if its not your own farm or one you work on and its not somewere close buy, they may not be to happy, they would need to view the land aswell and if its another force constabulary from were u live it might cause alot of hassel for u, even though 22c isnt that powerful they are still ******* dangerous, with rifles u never shoot unless u have sufficent backstop so shooting in to trees is a no no, but as was said shotguns are a much shorter range and the shot looses velocety very quickly, also with different chokes and shell type you have alot of freedom to get the sort of set up u like, be it a wide short range or a tight longer range, decoys are your best bet and a hide, pop downs some decoys and wait , they will come, and u will find the blighters are good sport and taste amazing, u can also use a shotgun for clays and lampng localy to were u live, there shood be shooting grounds nearby, but u can only use the rifle when u have sufficient land and they r less versatile for use, i have smaller and larger caliber rifles, i use a tikka tactical .308 for deer stalking a 22 for some pestcontrol but i use my shotguns all the time for just about anything, wildfowling, lamping pest clays etc, so after all the waffle get a shotgun they r far more worth it.
