Another LFP that has been available for years, but considered too long for the Grendel.
The Barnes web site provides load data that show 2500 fps from a 24 barrel using 28.0 gr of H335. I also achieved 2500 fps from a 24 barrel using AA2520. Subtracting 100 fps to account for barrel length, this 120 TTSX should achieve 2400 fps from a 20 barrel.
I was not able to recover a 120 gr TTSX from gel shots. But using the data from the 100 g TTSX, the minimum velocity would be about 2000 fps. Because of the relatively high minimum velocity and mid range BC, this would result in an effective range of only 200 yds.
Below are load data from the Barnes website for 115 and 120 gr LFPs:
