Out of your guns ill tell you the uses i would use them for.
SKS would be a plinking gun since ammo is cheap.
Ruger M77 would be my deer gun since its a larger cartridge and has a flat trajectory.
.222 would be a varmint/predator or target gun.
.22LR would be for target practice and squirrel and rabbits.
Shotgun would be used for abou anything as long as you use the proper round in it.
