I'm looking for anyone with experience with encore single shot barrels in 243 . I have one and am going to start loading here pretty quick. I have a rediculous amount of 100grain hornady spbt bullets . They shot very well out of a Tikka with a 10 twist. I'm hoping to use these and possibly the 103 eld-x . The later is the one I really want to use for hunting . Does anyone have any experience with these or heavier in a 10 twist ?
