I'm looking to purchase a pair of Saiga rifles for SHTF type scenarios sometime soon and am wondering how to get them chambered. The options I am considering are 2 in 7.62x39 or one in 7.62x39 and one in .223. Any opinions? FWIW, I have an SKS already. As far as I can see: Pros for 2 in 7.62x39 One ammo to stockpile Spare parts in case one breaks Two guns with better penetration Pros for 1 in each Alternate ammo in case I can't get 7.62x39 Lighter recoil for wife One gun with better long range accuracy? A variety of "tools" Feel free to add or correct me. Thanks.
