differences in a .300 win mag shooting 180 Barnes X and Barnes X triple shock?

I have heard that the TS will produce less pressure at the same powder charge, with the same velocity.

Hmm, I hate to try the theory that if some is good, then more must be better, without some data to back it up.

Part of me wants to bump up the load a bit in order to gain a bit more speed, but not at the sacrifice of safety or accuracy.

thanks in advance
