they would have to need a 1:7 or faster twist.??
I know trueflite do a 1:8 barrel in 6mm and mine certainly shoots the 105-108 gr bullets fine.
Have seen the velocity numbers the guys in the US are getting from 243/243AI shooting 115's and you would gave to think the pressures are up their.

PS, just to put it out there, on the 6mm BR pages they are claiming shooters of standard 243 cases are getting >3150fps with the 115 DTACs. Which gives better performance than the 260 rem or 6.5-824.
