I would too. Only 5 rounds and more operating steps to sight, range lock and fire. Definitely not for rapid fire if your trying to be effective. Bet the rounds are quite a bit more expensive too! $500 per round??
Given that from the US Civil war up to Desert Storm the average number of rounds fired per enemy dead remained nearly constant at ~100,000, $500 for a practically guaranteed kill is a bargain.
We at FR, have had the M-16 vs. .308 argument till the cows come home. The .223 argument was that the round was lighter, so you could carry more, Smaller, so it costs less, and was fast and accurate. Always the last comment would be, “Well, I know you are but what am I” and “Look what they ended up choosing”. Now, I’m supposed to believe we need a gun that holds 5 rounds and the ammo is made of gold with platinum pinstripes? Nothing wrong with experimenting, but when it comes to war, cheap and plentiful usually wins.
