The published max Barnes TAC loads for 308 Win (51.2gns) and .30-06 (53gns) with the 130gn TTSX produce 3246 and 3165 FPS respectively. Both of the test barrels are listed as 24". I am curious as to why the '06 is almost 100 fps slower with 1.8gns more powder? Is the velocity difference due to chamber pressures?
I have direct experiences with the 308 Win. TAC load and have produced similar (sometimes faster) velocities. I am getting approximately 3248 fps out of my 20" barreled Bergara and 3126 fps out of a 16" Rem 700 LTR both in .308 Win.
