I've got an 11" twist Broughton bbl in 300RUM. I can get .5moa from the 208 A-Max but only .75-1.00 moa with the 210 VLD's. It's likely that the 210's are stable with the 11" twist but that I just haven't found the right load or that my rifle just doesn't like them. ???
The 190 SMK bullet has shot in the .1"s on several occasions.
