Looks like you could get a little more velocity out of your barrel by going to a higher charge or different powder. Typical velocity with a 120 grain bullet in a 20” 6.5 Grendel is about 2475 to 2520 FPS from my testing.
+1 ^^^ what he said.
Also with the longer barrel you could get some more ooomph with a slower powder... like maybe cfe123.
Seems like a 20-22-24" barrel would get you what you might be looking for.
One more thing, the 120 ttsx with a G1 of 0.412, doesn't have what I would call a 1000-yd BC... for bangin' steel why not go to a better-BC bullet. 129 Ablr, Hdy 123-anything, lapua scenar's, sierra SMK's.... lots of 1000-yd choices.
