Ole 270--
I recovered two 210 gr TTSX from a dirt bank at 400 yards. Those bullets looked indistinguishable from the two shown in my photo above; in fact, their expansion and weight retention were part of the reason I subsequently used them on a very important hunt. Based on a muzzle velocity of 2880 fps, the velocity at 400 yards should have been around 2025, based on a ballistics program. The velocity at 100 yards should have been 2665 fps. So if the 338 Federal can get that bullet going 2665, then it is my 338 Win Mag load, minus 100 yards. So it should get that same terminal performance at 300 that I got at 400.
If the 338 Federal can only get 2435 fps, then it is my 338 Win mag load -200 yards.
