I have been shooting 130gr. tsx not ttsx dont think load will be much different though. Using norma brass, Win mag primer, 75gr. Accurate Magpro. 3500fps. Be very cautious if you try this load I am over book max values, but In my rifle I am just starting to see pressure signs. I have found this to be an amazingly accurate load. This is being shot out of a Browning M-1000 Eclipse 26" barrel. I have found my best accuracy to be much closer than barnes recommends though.
