Re: Twist rate and bullet stability at 900 yards
If your after high BC, look at the 180 Gr Berger or the 180 gr JLK.
This might just be the answer for you.
Their BCs were in the .7 range.
I had some 187gr 7mm Cattarucios years ago that really held up well at extended range in my 7/300 Weatherbys.
Same jackets as the Sierra MK.
You don't need excessive speed with a 180 gr plus grain 7 mm match style bullet.
PS---If I had a 7mm RUM or the 7mm/378 Weatherby, the 180 gr bullet would be my main bullet of choice.
