I have obtained excellent results with the 110 and 130 gr TTSX bullets. I settled on the 130 gr just because I'm old school enough that I like more weight.
You may want to try H4350 with the 110 gr bullets. FWIW, it has been my experience that I get my best accuracy when using the TTSX bullets near the high end of the velocity range. With the 110 gr that is in the 3500+fps range. For the 130 gr TTSX I am getting my best accuracy with RL26 and ave velocity of 3333fps.
Sizing die issues are not uncommon with the WSM cartridges.
