Took out an old Vanguard .308 today to test some 130gr TSX and TTSX. Suffice to say it was a dismal failure. Had mounted a new scope so took one shot at 50yd which looked perfect. Went to about 125 and fired 3, only 1 landed. Figured I was shooting high since I saw no splash, so held low and got a hit that was clearly keyholed. This was a TSX with full case of Varget.

Tried the TTSX with the same load, only 2 hit paper at 100 and both also keyholed. I'm guessing the ROT is just too slow. I tried measuring and it seems to be 1 in 11, close as I can measure. According to the Barnes site that should be fine. Any idea what is going on here? This was going to be my elk rifle this year, but looks like its going to be either the .375 or .243 instead.
