The last famine, the first supplies I saw in pistol were S&W .40, in rifle, .308...long before .223 in these parts. .308 is a nato round, tons of military brass even if not the best for long range purposes. .30 caliber bullets abound. Where was the 6.5 CM? I must have missed it around here.Based on historical data the opposite would be true.
