I'm loading for 2 different Tikkas in 270 wsm with 130 gr TTSX. Have tried RL22, RL19 and now H4831sc. I'm getting my best groups with the H4831sc so far and was wondering if any others have had success with this. Everyone I have talked to said Rl19 is the go to powder for a 270 wsm but I'm not seeing it so far.
