OK, well now that you have three farm rifles, you may find that you have a problem. I lived on a 45 acre farm with mixed woods and fields for 14 years. There were lots of critters, small and medium, that were turning up around the house, in the 2 acre yard.
What I found was that if I had more than one potential farm rifle in the rack, then when I ran in to get it to dispatch a critter, I got brain freeze. I wasted valuable time starting at the rack, trying to figure out which rifle would be the "best" for the critter and range at hand, and them fumbling for different ammunition. Meanwhile, the critter was getting away, or getting out of range, or getting closer to the house.
Finally, I decided to only have a .22 LR rifle at hand, with hi-power rounds, with copper clad round nose bullets, sporting a 4 power compact scope. This turned out to be totally fine for everything. I knew exactly where it would hit and for how far out. If I didn't have time to grab muffs, then the occasional shot would not create too much damage to my ears.
I highly recommend that you use this method. Morover, if you choose to go the .22 Mag route, then you had better always have those muffs on, because it is extremely loud and will do quick and serious ear damage!
Just my experience.
