We know that M193 will penetrate most Level III steel armor when fired from a long enough barrel due to its higher velocity. Winchester 45 gr varmint JHP can generate even more velocity, about 3,500 fps from a 20" barrel, but it obviously has much lighter construction. So here's the question: Will that tiny little bullet still have enough mass to get through? If so, which barrel length will do it? Multiple poll choices are allowed so cast your vote for the barrel length or lengths that you think have enough oomph to get through. You know the drill, place your bets.
