I don't understand it. The price for cheapo Ruskie 7.62X39 is approaching twenty cents per round and approaching that of cheapo 9mm. The price is almost half of what 7.62X57R is selling for. At the twenty cent per round price point, a conversion setup makes sense to me. The only downside I can see are the links. But, who cares as long as they are reusable. I haven't seen any interest in this conversion setup even though it is already engineered, worked out, and available. What am I missing here?
