I don't practice for/or compete in any kind of marksmanship events or anything. I only practice for self/home defense so I only practice from point blank to 20ft. Once in a while I'll fire off a few at 30. For my situation I can't imagine a senario where I would be defending myself from someone who is over 30ft away. When I practice I fire at least 100 rounds out of all my guns. In my primary weapons I fire anywhere from 500 to 1000. I would love to practice with the same JHP's I keep the guns loaded with, however I'm not a millionare so that's out of the question. I do shoot at least 5 of them off from each gun at the end of the day.
A hit with a .45 ACP beats a hit with a .22 LR everytime. A hit with a .22 LR beats a miss with a .50 BMG everytime.
