[QUOTE="royinidaho, post: 391300, member: 2011"] Hmmmmm, MVs would be helpful. Would give indication of velocity overlaps between different powder charges. Statistically I would venture to say that there is very little difference between the 243's groups. The group where shots 2 & 3 about went into the same hole (46.3 gr) would make one feel good but the odds of it happening are pretty decent out of that many shots where group center hasn't changed much. If it were me, I'd do another test starting with 46.2 gr, increasing 2 gr until you start getting pressure signs. Using CCI 200s instead of the 250s. And, if at all possible chrono each shot. The reason I suggest CCI 200s is that I shot 250s for decades in a 270 Win and consistently shot 3/4 MOA average groups. I was suggested that I try the 200s and waalaaa groups shrunk by 50% consistently. You may not be able to shoot the higher powder charges due to pressure. Just pull those bullets. Again with the 300 I don't see much difference between the groups. [/QUOTE]
