Velocity is always a concern so I figure this screen shot could help out others that come along wondering about charge weight and seating depth. The above velocities are from bolt guns.
Weird. I don't hand load, but just under 2600fps is what I get from the black hills 5.56 load out of my suppressed 12.5. 16" pushes them at just above 2700fps.I was a little under 2600 fps with 77 TMKs in my 16" AR and it was hot. I can't imagine getting 2700+ with any powder. That was a 5.56 nato chamber with CFE223 but I don't remember the load weight off the top of my head.

Send them a link to this thread, and tell them to get hot on changing their dumb laws.223 isn’t legal for deer or big game where I hunt. Still, I have waded through this thread (took me several sessions!) and I have found it informative and interesting.
So thanks for everyone who has made constructive posts in it.
The TMK seems to punch above its caliber and is a formidable load.
Seeing mention of this thread on snipershide is what brought me to rokslide.
I shot a lion with one, and my wife shot a buck with one, and a few coyotes (smk 77gr) and certainly had mixed results… everything died, but some of them didn’t disrupt, some did.Those perform pretty poorly on game. I’ve shot a ton of groundhogs with them, some coyotes, and hogs and one small deer and they usually don’t expand or fragment at all, usually they just pencil through. I lost the deer and several yotes. Groundhogs usually required multiple shots too. I’d say maybe 20% of the groundhogs shot with them they fragmented.
I’ll still use them for groundhogs and pests in a pinch but I still prefer them to not suffer and no way would I use them on the animals that people in this thread are shooting with TMK’s.
This was my thinking. TMKs are hard to find. Save them for hunting. Shoot these up at the range.I buy 77gr SMK for practice, etc. Save the TMKs for bloodletting.

The TMK is a great bullet across the range, really. Next to the ELD-M, it’s my favorite “do it all” choice.
My own experience with SMK vs TMK tracks the conventional wisdom concerning tangent ogive “traditional” bullets and secant/VLD ogive designs. For me, the TMK have always exhibited sensitivity to “jump” - so much so that I’ve experienced three different powders and multiple charge weights shooting ~.65” average per 5@100 when it’s right and refusing to group under 1-1.5” when it’s not.DJL2,
I’ve shot some really tight groups quite consistently with the SMKs, but the TMKs seem to not do as well. But, for hunting or defense, a 1moa rifle/ammo cmbination is probably just as good as .75moa.
Cheers!
