I would like to express my appreciation for the work you put into that ! Read it years ago even before joining the fourm and still like to reread it every now and again.

Hear, hear!

62/64 grain Gold Dot







10-shot group of hand-loaded 62 grain Gold Dot:  extreme spread = 0.58”





Nosler 64 grain Bonded Solid Base




Terminal ballistic testing conducted by Dr. G.K. Roberts using the scientific standard of properly prepared and validated 10% ordnance gelatin has shown that the 64 grain BSB can produce an average penetration depth of 17.1” in bare gelatin with a recovered diameter of 0.46” (when fired from a 16" barrel.)  After passing through an intermediate barrier of automobile safety glass, the 64 grain BSB can produce average penetration depth of 13.6” with a recovered diameter of 0.35” (again from a 16” barrel.)

A Sincere thanks for your time and effort.  I'm not going to quibble.  
I have been reading this stuff since the Ammo Oracle, Troy, etc.  

Unfortunately, the 77 grain MatchKing does not have reliable terminal ballistic properties compared to the 77 grain Nosler OTM, 75 grain Hornady T2 and the 77 grain Tipped MatchKing.  It can have an excessively long ballistic neck and a lower percentage of fragmentation compared to the previously mentioned bullets.



…

I treat all of the 75/77gr SMK's and OTM as better M193's in terms of bullets that CAN, and often do fragment via yaw, but were not specifically designed to do so.  Thus the necks could be longer than something that was designed to break apart.

I consider the TMK heavy varmint rounds, which were intended to fragment.    Of course velocity plays a big part in that as well.

I loaded up on mostly 77gr IMI SMK's prior to ACC selling TMK's that are actually affordable.  (But I don't shoot any of them now).

Ive founs 77 TMK to be about a 2.5-3moa round so its mainky for bigger closer targets for me.

Something is not right with that.  My hand-loads with the 77 grain MatchKing have produced sub 3/4 MOA 10-shot groups.  The original lots of the Black Hills 77 grain TMK were a little over 1 MOA and the newer lots have turned in some sub MOA 10-shot groups.

I've shot it in multiple guns. In all of them, I average 3moa or so. In the same range session as Browntip, MK262, etc averages 1.5-1.8. Of course, I only use chrome lined LW barrels, so there is that. 10 shot groups.

Every year or two, I buy a new 50rd box from Black hills. In every case it continues to return the aforementioned performance.
