    77 grainers no good for my 1/9 twist?

    I have 500 SMK's in 77 grain .224 I bought for a 1/7 twist Ar I had. I guess there is no point in even trying to load them for my new Rem 5R Mil Spec Rem 700? Any of you guys loaded 77 grainers for a 1/9? Guess I should trade them for something more appropriate.
