Sierra Heavy TMK 6MM Testing

[Formidilosus]

Well….

116gr TMK’s are absolutely devastating. Even at mid impact velocities- 2,500-2,000fps, they produce wounds that I haven’t seen since 178gr AMAX’s.

Maybe a dumb question. But are they too devastating? Would it be better to go with the lower weight 6mm TMKs?

Based on how you’ve described the Amax in the past, is it too much of a good thing for general hunting?

Anyone shooting a 6UM for insight on performance at or above 3k fps impact?

Yeah, I might stick with 95 gr TMKs. I don't love the amount of damage from a 77 TMK.

Perhaps load some 116s for brown bear and moose.

Has the 6x45 seen action then?
I'm curious to hear your thoughts on this combo.

Any thoughts on min impact velocity yet?

Appreciate the info Form.

I am curious how the terminal performance compares between the 95, 107 and 116 inside 300 yards.

I kind of assumed the 116 might turn out to be less violent on closer shots due to slower MV.

I’d love to hear more about the elevation at which you are shooting and the twist rate on your rifle.

I don’t think I want to know what those 30 cal 220s would do…. That 95 tmk alone absolutely blew me away this year on a cow elk shoulder at 680 yds just above 1900 fps impact velocity.

 

[wind gypsy]

I mean for a given cartridge there's maybe two or three Viht powders that will be in a velocity range I like.
But with Hodg there can be quite a few more.

I think there are just as many or more viht n1XX/n5XX powders in a given burn range than Hodgdon extreme powders.

Tipped Murder Kings?

Will the 116s stabilize in a 1-8” Tikka .243?

I was thinking Terminal Murder Kings

Someone has to shoot an antelope with a 220.. for science

 

[DangerRanger]

Boy would I love to see a 6creed 116tmk federal gold medal load

Probably wouldn't be anything left to document haha.

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

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.






Heart-

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.
