I like short rifles and seeing this Ruger offered in several calibers has me curious and interested. In a 16.5" bbl, .308, 7.62x39, 7-08, .243, .260? I'm liking the .308 for power and availability, but would there be too much flash and bang? Would 7.62x39 be a perfect cartridge for this length bbl? I think it would be a nice 100-200 yd gun with a low 2-7 power scope. What are yalls thoughts?
