Sierra Heavy TMK 6MM Testing

Or a 107 6mm ARC load... Mint.

I genuinely think a 107 6 creed load is realistic and would be enough for me. That arc would be nuts for AR world though

I would like to do a 107 TMK at 6mm ARC bolt action pressure. Should be able to get 2600+ from a 16" based on what can be done with 108 ELDM and 108 EH and a bolt action 6mm ARC. Should kill right nicely.

Remember this is culling. Not hunting.

If you just hit ribs, it’s good- very effective.
If you hit bone, very likely you won’t like it.

2,100’ish FPS impacts. Photos and animals are unmodified.

Quartering too- shot entered center chest… How we walked up to it. A 9-10” wound.

Facing directly away. 2,105fps impact. Entered center of rear ham- 10+ inch hole. TC blew stomach out mid belly, bullet traveled all the way through the chest and through the heart. Everything inside body cavity was wrecked.

Yes. It’s effective.




Nothing definitive at 1,800fps they are devastating.







They’re all messy.





No.





-3,000ft DA. 1-7.5” twist for most of the guns.

Thank you for the reply. Have you, or anyone else, tested them in a 1:8” twist Tikka? Do they stabilize in it? Or need a faster twist?

I’ll shoot a Tikka 1-8” 243win this week. But yes, they will work in a 1-8”. I can’t imagine how they wouldn’t.


The 88gr .224 however, did not work at -3,000ft DA from a 16” 1-8” twist 223. grin

@Carl Ross posted about shooting them in the .243 without issue, I believe. Earlier in this thread.
