Three year old thread and still not resolved. R26 is my new go to for medium sized cases .243 to 300 WM. Follow MD's advice and you will find bliss. I can get there or close easily with a 24 inch barrel and R26. Many are reporting good velocities but not exceptional accuracy. I think the potential is there, treat it like a slow or ball powder, try magnum primers and it seems to like the sticky bullets or those with a long bearing surface to even out pressures. I am not picky and usually quit when I consistently get groups of an inch or less. Others may be more picky but I don't shoot anything but rocks at extreme ranges.
