Black Hills tipped SMK's 77 and 175

[BufordTJustice]

Bare gel and barrier tests:

I'm quite impressed. That's devastating for an unobstructed shot.

I shot a green tip into water here at home. I kinda felt that the frag was TOO good out of an 11.5. I prefer the regular OTM's deeper penetration... although the Green tipped bullet would certainly do a number.

I dont much stock in water tests other than to answer the question "Will it frag?" Water tests tend to over exaggerate fragmentation and expansion. What really surprised me was how deep this penetrated in gel, 16" is pretty damn good for an OTM and it even did decently through barriers.

Bare gel and barrier tests:

Clear Ballistics Gel is not a valid test medium and the scientific literature has shown that "energy transfer" is not a wounding mechanism for small arms fire.

100% correct Molon. While 10% ordinance gel is ideal clear ballistics gel is better than nothing. Also I think the real strength of the clear ballistics using it to compare a good performer that has existing ordinance gel data and comparing it with an unknown bullet and seeing how close it comes.

For example, the same youtuber made another video with hornady 75gr TAP using clear ballistics which already has plenty of ordinance gel data which we can compare directly to the performance of the 77gr TMK.

I agree. But it's relatively easy to do a water test... and you get some comparability from load to load.

It would be nice to be able to buy a gallon of gel for $1.00 or .02.

From Applied Ballistics Facebook page. Also, Litz says they will be testing the 77 gr TMK soon (they are in the mail).

Thanks for link, Gamewarden. Keep us informed. Alot of us are dying to know whaht Litz is for 77 TMK and 175 TMK.

175 TMK is listed already
