I am looking at the 270 Win page in Barnes # 3, and there are no accurracy loads listed for the TSX.

Best thing you can do is to just try different powder combo's to see what works.

So far I have found TSX to shoot better groups than the old X bullets.

Do they list any accuracy loads for the 130gr X bullet?

Yes, for standard 130 gr "X" 54.5 gr Rel 19 for 2936 fps,

For Coated XLC BT they show 57 gr Rel 22 for 3041 fps, and 57 gr IMR 4831 for 2967

I've been having good luck with 61.0grs of RL-22 and a BMU'd 130gr TSX, WW Cases and Federal GM210M Primer. Here is a 300yd Group from my lightweight 20" barreled Sako Finnlite.......




At 100 yds this load usually shoots bugholes........DJ
