[QUOTE="Fiftydriver, post: 326710, member: 10"] We had problems with the 3 groove barrels and that twist at around 300 rounds but we were also chambering them in the 7mm Allen Magnum which adds around 500 fps to the Rem Mag. I think you will have much better results with the Rem Mag because of its lower velocity ceiling. I still suspect you will run into issues sometime down the road with that fast twist but if you do, just jump over to the 175 gr SMK and they will hold together for you. Their BC seems to be right around .670 as well which is better then they are advertised to be. If you need a second option, that would be a good one. Keep us posted. [/QUOTE]
