Gents, I have never been able to get either the TSX or TTSX in 180gr to shoot well in my Tikka T3 in .300 Win Mag. That rifle will shoot just about anything else at MOA or better. I did get loads that were accurate enough for hunting at reasonable distances, but really it would be better to in that rifle with A-Frames, Partitions or AB's. Today at the range with my M70 in .300 Win Mag, I shot some TSXs and TTSX's, 3 of each. I loaded them up just for giggles to see how they'd do. Well the TTSX load was under MOA and the TSX just a smidge over. This was the first loads in these bullets fired in this rifle so who knows with a bit more work just how accurate these could be made? Now obviously these are two different rifles and the M70 has a 26" barrel versus the T3's 24" barrel. But I couldn't help but wonder if the difference was in the twist rate. The M70 has a 1:10" versus the Tikka's 1:11". So what do you think, is it the twist rate?
