Black hills has stated that the tmk is getting 12" of penetration along with fragmenting down to 1920 fps IIRC, and they still have not found the lower limit of that threshold. So this should be good for the people that want to use fragmenting ammo for sd. I hate all the bs with proprietary bullets though release them to people who can do something with them. Selling them to BHA only is garbage.
I think both BlackHills and Sierra are both top notch companies. I have used more Sierra bullets than all others combined because of their consistent accuracy in my guns. As a guy who roles all of his bullets, I really would of liked to have got my hands on a couple thousand of those. O well. It was worth a call to try.
I’m disappointed by this news. Sierra seems to have their head up their butt. Next match I shoot that they have reps at, I will get on them about it. I know tons of people that are wishing Sierra would make a tipped match bullet. Hornady does a much better job of responding to consumer demands. Currently, I’m using the Hornady 75 gr BTHP (A-max just won’t seat deep enough) for precision rounds.
I’ve gotten them to shoot great. I posted a picture of the first two groups out of my BCM KMR13 16" 410 SS upper in one of the threads. I managed to shoot in the sub 1/2 MOA range for six or seven shots before one went out. The round that went out was just a bad shot. I did it with a 4x Trijicon.
Out of my 18" WOA barrel, the same load has been a .75 average gun over its life thus far.
LC brass, trimmed to length (chamfered/deburr in same process), primer pockets and flash holes uniformed, CCI 450s or 41, 24.5 gr Varget, loaded to 2.26".
I use Redding Type-S FL dies and Forster BR seater dies. It’s been a good combination so far. It doesn’t do so well on a progressive though.
Great news no matter what (and I’m sure they’ll be available to Joe Handloader soon enough). Yesterday I’d have been repeating the decades-old mantra, “what could be better than the SMK (in the category of production bullets)?”
