I have shoot several different name brand rounds and have found out my 243 doesn't like Remington core lock rounds. Set scope with hornady rounds with good groups. Used core locks and they were all over the paper target. Went out next week with monarch and had good groups again. All were 100gr. Started reloading my own rounds with 95 and 100gr. Hornady. Good groups. Has anyone else had this problem or is it just me and my gun?
