Tried them in my 9 inch twist .243 AI . Couldn't get them to work at over 3200 FPS . Have read that 3150 is their accuracy limit . Too slow for me . Have a reputation for being a finicky projectile .
The 88 gn low drag is apparently easier to get good accuracy from . If you have an 8 inch twist you could look at the 105's / 107's . A Max 105 will work in a 9 twist .
