Use what you got, use it as well as you can, don't over gun yourself, a large bullet miss is not as effective as a small bullet hit. That being said I am a larger is better guy and I don't care what the muzzle velocity is, I'm not fast enough to duck a large slow moving 850 fps bullet any more than I can duck a 3200 fps bullet and I bet I'm not the only one.

Good intentions will always be pleaded for any assumption of power. The Constitution was made to guard the people against the dangers of good intentions. There are men in all ages who mean to govern will, but they mean to govern. They promise to be good masters, but they mean to be masters.
