Sherm,
I think you should try RL22. I just got back from the range today and I shot 3 into 7/16 w/ 72 gr and a 100gr TTSX at 3680 from my 26" Broughton #4 barrel. It does the same ar better with the TSX or you could use the 110 Accubonds and 7828. Seem to recall getting 3400-3500 before hitting on the RL22 load.
