Its a lot different in the states to back here in Wales and the rest of the UK. We cant trap any more using snares, the biggest springtrap would be a fenn mk6 which would be 6" square for rats squirrels weasels/stoats and then they have to be covered so only these animals are caught, we can use cage traps. The smallest cal for deer would be a 243 even though a 22/250 or 220 swift would do the job on anything we have in this country, although you can use a 222 for small deer species roe/ muntjac in scotland. if we had a job killing predators and antiblood sport people found out windows would be smashed and if we confronted them gun licences would be lost, you guys are lucky, very lucky, we are limited to ammo to guns even calls are banned to shoot some things, we cant even kill a rat (a 4 legged one) with a bow or crossbow, but can with a catapult, air rifles are governed with a 12lb limit or they will need a firearms licence, if we were seen with a bowie knife we would be surrounded by armed response police, im nearly 69 so i can remember days of old before all these rule changes when people would eat wild things that were shot, i go out some nights shoot 80/100 rabbits and have to leave them there for the foxs and badgers, Even pheasant shoots cant give the shot birds away to many vegans here, god help us if we get a vegan Prime Minister or Charles turns into one
