Sierra Heavy TMK 6MM Testing

Huh, didn't know they issued TMK ammo at all. Interesting and thanks for sharing.

What do you think the 77 TMK was designed for? Hint: two legged targets. Marketed as a “match” bullet so that it’s useable. It’s not a “hunting” bullet

I've been loading TMKs since they were released in 2015, started primarily with 77s from an AR. I had never heard that claim until recently on this forum. Have always known that they perform well in that regard but never that they were designed for it. Got receipts?

Lots of 77, 6.5, 168, 175 SMKs used in matches and these were a higher BC version so its not like they didn't make sense as a match bullet.

I wouldn’t want to put words in his mouth, but Form eluded to this on a podcast.

The whole bullet thing has been more or less hush hush in industry and military. Look at the original twist rate on the AR platform 1:14. 55g bullets would upset upon contact and thats where you got the "bullet tumble killing" of Vietnam.

First deer with a 77g OTM solidified it in my mind that the design intent on those bullets was apparent. 69g mean greenies(green tip steel core) are mostly for punching through obstacles to hit target on the opposite side but that hard impact will still cause a level of disruption.
