[QUOTE="WildRose, post: 1194998, member: 30902"] You might want to reread and edit. You're recommending the same 1:8 twist for both the heavies and the 55's. Berger recommends 1:12 twist rate for their heaviest .22cal bullets and 1:15 for their lightest .22's. According to Nosler 1:12 is the standard for the caliber but suggests a faster twist for their 60gr. I find another chart that isn't attributed to anyone in particular from another forum that suggests 1:7 for .22cal 90gr bullets. The more I look the crazier it gets! Did you mean to say you were going with a 1:7 for the heavies? [/QUOTE]
