I have gotten to where the "norm" doesn't excite me anymore. 308, 270, 7mm08, 30-06 are just plain boring and everyone and their brother has one. Show a buddy your deer rifle and odds are they or someone they know has the exact same gun in the exact same caliber. I own a few "common" calibers and love the 243 in particular, but I'm looking to add to my collection of "unique" rifles and calibers. Right now, I have a Ruger No. 1 RSI in 257 Roberts and that's about as unique as I can think of. I also have a CZ 527 in 22 Hornet.
I'm thinking about carrying the 22 Hornet this year for deer season for doe culling on my property. I'm thinking a head or neck only shot should do the trick on a doe.
But what are some other unique calibers that are low recoiling that I can start looking to add to my collection?
