[QUOTE="MuleHunter, post: 248344, member: 14190"] There is a guy named Brian Litz who is a competition shooter and a ballistitian who goes into great detail about the 180gr berger VLD bullet. Here is a link to one of his articles [URL]http://bryanlitz.bravehost.com/articles/7mmNumberOne.pdf[/URL]. According to him 'optimal' twist rate can vary depending on conditions, the worst or coldest (0 degrees-0% humidity) being 1-8.7" twist, and the best (100 degrees-100% humidity) being 1-10.5" twist. A buddy of mine shoots a 7wsm 9 twist 3 groove and it does exceptionally well at 1100yds i don't think a half twist would matter too much. Interestinglly enough Brian Litz uses a 1-8.7" twist barrel in his test. [/QUOTE]
