[QUOTE="Warren Jensen, post: 20801, member: 21"] Brent, As Dave said, we need some basic information. I need all the things Dave asked, plus what is the twist of your barrel? Also, how reliable are your chronograph readings. Have you calibrated it? Have you used other chronographs to check it? What shape do your bullets print on the target at the various ranges that you listed? Very few bullets will print perfectly round holes at all ranges. Thanks [/QUOTE]
