I've shot both the 165 g. factory .308 and the 180 gr. factory 30'06. The .308 ammo, both the original TB and the TBT were no better than 2.5 MOA in my M70 Stainless Fwt. But the 180 gr. '06 stuff shot right at MOA out of my custom 98 Mauser w/ Pac-Nor barrel.
I've pulled the bullets of both the TB and the TBT and tried to reload them. I could get the original TB to shoot very well in my M70 Fwt. But the TBT I found was so slick, I couldn't even crimp it into place and make it stay put. Nickel plated bullet.
I've killed stuff with both the original TB and the TTSX. Yes, they expand readily and penetrate very well. You can eat right up to the bullet hole with both.
So, as far as I'm concerned, if I want to use the TBT, I'm stuck with factory ammo. I can reload the TTSX. E
