Anyone shooting F-Open with a .22cal round other than the .223R? Am thinking mostly mid-range. Just read an interesting article on blowing out the .204 to .223 which gives about 5gr more powder than the .223R. Shooter got about 3125fps with 69gr SMKs. Probably around 3000fps with 80gr and 2850fps with 90gr. Might make an interesting round.
