I have plenty Nosler 7.62x39 (.310 Diameter) 123 Grain FB tipped (jacket) bullets that would last more than a life time, bought when it was cheap. I load and shoot them in my 308 bore 7.62x39 bolt gun and AR but I wonder if it would be OK to load them in 308WIN and shoot in my 308 bolt guns? 308 bore 7.62x39 likely have deeper throat and lead in than 308WIN, OK in 7.62x39 with 308 bore may not be OK in 308WIN, but .002" is really nothing. Any experience?
