Any using barnes 130gr TTSX? Have found one load that stays moa to 300yd, but never any spectacular groups at 100. Could it be the 1:12 twist holding it back? I would not think that to be the case, but many have more experience than me.

130gr TSXs (haven't tried TTSXs yet) have averaged .957" at 100 yards for every load I have tried through with. Not too bad, but not nearly what this rifle will do with other loads. Interesting to me that neither seating depth nor powder charge have made any definite difference in group size. My barrel is a 1-11" twist. I kinda doubt twist is the issue though. I haven't stretched them out to 300, but probably should. MOA to 300 isn't too bad...
