Thread: .30 cal 1-7 or 1-8 twist barrel

I run hardy barrels in my comp gun and 7 saum, absolute tack drivers, my mate has probably 9 of their barrels, 2 300norma (ones a norma improved now) included, he runs the 250 atips in the 9 twist no issues. Definitely no problems with accuracy. The stainless barrels seem to be very forgiving in my experience and the carbon wrapped a touch more finicky but still no dramas to get shooing very well
