Does anyone have reliable expansion data on the TMK for 16" barrels? Using Black Hills 77gr TMK

I've read reports of 300 yards to 350 yards, seems shallow though for the TMK.

Thanks!

Use impact velocity, not distance. 2000 FPS to be safe, 1800 FPS if you want to stretch it, though it appeared to upset well at 1440 FPS.

Stop thinking of platform or barrel length and think muzzle velocity. So many variables in your question. Shooting an animal at 350 yards from a 16” barrel at sea level and shooting 350 yards out of an 16” barrel at 7000’ will yield different velocities.

Your impact velocity will be influenced by your location and conditions. Figure out what your MV is, and you can utilize your conditions in a ballistic solver like shooter to give you a range where your impact velocity is at 1800 FPS or above.
