Hi, my name is Luis, from Puerto Rico and want to know is there a formula or something to determine how many turns the bullet turns intothe barrel? I mean, i own a ruger 77/22 bolt action rifle with 24" barrel and 1.16 twist. I think the bullet rotates 1.70 turns in the barrel. Am i ok? Also i own a forum in Puerto Rico, www.shooterspr.com you guys are invited to share with us your experiences in shooting sports, and regulations you havein your country. We have a foreign visitors forum, so register and enjoy! Thanks for your attention and help related to my rifle!
