Crazyis,
Why would you want to switch from a bullet that you know works for you? I could see if you are a handloader because we are always tinkering, according to your post you are shooting factory loads. I have no personal expierence with the GMX but have not found anything that will shoot as good in my rifles with the performance to boot as the TTSX. Good luck with your decision.
Yes, I shoot factory loads and found the Hornady 165 grain GMX rounds to be very accurate out of my rifle. It appears to me that Federal may be dropping the TSX line in their rifle ammo and want something to fall back on. Also, I don't hear much on people using Hornady bullets for larger game.
