Fred, I too have been very happy with IMR 8208 XBR. Haven't had any groups in the .2s, but I don't think I can shoot that well
. But I have also found that it is a very consistent, well-behaved powder, that meters very well through an old Redding 3 measure. I have not exceeded the book maximums in commercial brass, but have found that it likes to be near those maximums. That said, the starting loads grouped well too. Shooting 50 grain bullets (either Nosler Varmegeddons or Hornady V-maxes, forget which), 1/2 grain under max, put 10 consecutive rounds in 1.3". Didn't think that was too bad for a prairie dog gun! With that load, 5 shots usually go well under an inch.
