Barnes recommends that you use the data for the original "X" bullets for the TSX. At least until they produce tested data for the TSX. I just figure I will wait for the tested data before I try the bullets. I have heard of people exceeding the recommended loads and even exceeding the loads for the other high performance bullets that Barnes warns will cause dangerous pressures. I suppose if there is no published data for a bullet then you can load it until it blows the gun up.
