I haven't been able to find this on the web, but would like to know some powders and charges for a 280 AI using Barnes 140 gr TTSX?

Thanks. donsm70

Barnes recently added .280 AI to their load data. I've had good luck with H4350 and H4831SC.

I have had good results with R22 and VV 165. But R26 is looking promising and will produce slightly higher velocities.

Use 60-62 gr. R26 for about 3200 fps in a 25 inch barrel.
The TTSX produces less pressure than some other bullets because of the ridges but I haven't really leaned on it yet to see if I can add more powder. Go slowly as R26 won't show any sign of pressure until you are up to a proof load, especially in an AI cartridge.

I've been working with VV N165 and the 140 TTSX. Early results are very promising from my Cooper. This load is pretty hot in my rifle, so back down to start.
