R93 300 RUm standard barrel twist rate
Good morning Gents: I have seen/ read two different sources with conflicting information about the twist rate on a R93 RUM standard barrel. My ammunition manufacture recommends 1:10. Nosler ABLR 210 gr. so I know a 1:9 is fine, but 1:11 might not work out so well. Can anyone help with some factory sourced information on the twist rate? Thank you David
