Machined 100% copper with a polymer tip to increase BC and aid in expansion.

Until this point, I have treated these two projectiles as essentially the same. The only measurable difference so far is the "X" on the bottom of the TTSX. Until I can get time to shoot the TAC-TX into gels.
The 100 gr Barnes has been the go-to LFP for the Grendel. Its only drawback is the velocity needed to open up and begin expansion. Gel results show this speed to be at least 2000 fps.
