[QUOTE="Canhunter35, post: 1784934, member: 101677"] I’ve been shooting a 1:8twist 7 rem mag with the 180 hybrids. It’s a 28” tube and my mv is 3052fps. I’ve corrected my curve to 1630yds, so I know my mv and bc is pretty close. Lately I’ve been taking 1-3 shots each day from 800-1300 yds, but my wind calls seem low, I’m basing it off my wind chart from applied ballistics. I’ve taken my 6.5, and shooting side by side I’m basically holding the same wind with a slower and lower bc bullet. So I’m wondering what other guys experience in wind deflection with using this bullet at long range. One of my theories is with the 8twist barrel I’m over spinning the bullet causing it to remain nose up when it should track down to the angle of attack. And this is causing the increased wind deflection. Just a theory, what’s your thoughts? [/QUOTE]
