I did not see this billet (or style of bullet) mentioned in the entire thread. Is it because it is not consistent?

What about frangable 223 / 5.56 ammo? I have only seen YouTube videos in balistics gel so I literally have nothing to say it will work... but look very cost efficient and like it would do the same thing (in theory) as a TMK...

Any 1st hand knowledge out there?


Edit to add: as long as it is still heavy for caliber! I have seen them at 45gr for a 223 / 5.56...

Which stability calculator have you all found to be the most accurate? My .223 bolt gun is a Bergara Ridge SP with a 1-9 twist barrel. It shoots the 73 ELD-Ms well, although I have only tried it to 300 yards so far.

JBM gives me a return of 1.51 with the 77 TMK, but the Speer and Bison Ballistics give me ~1.2. I run into the same results with the 73 ELD-M, so I'm questioning how much weight to put into it. I'm going to get some and just shoot them to see, but curious what other folks are seeing.

If it doesn't have a value to input for tip length it's going to be wrong on every tipped bullet.
Even jbm assumes plastic, if you have an aluminum tipped bullet it won't be quite correct either.
JBM is the one you want to use.

I'm not sure if these have been posted before & quite frankly, I'm not trawling through 390+ pages to find out. 😆

For those who're thinking or wondering why to pick the TMK over the TGK (the Gameking being a 'hunting bullet' after all.....)

That massive jacket difference is why the MK is so devastatingly effective & why the GK gives the mushroom, so beloved of the advertising folk.

That's what I suspected, simply based on the logic of more information = a better output.

Thanks!

I’m not a metallurgist but looking at the two jackets, the TMK looks like copper and the TGK looks more like brass. Could be just the picture. Does the TGK jacket seem harder, not just thicker?

Hypothesis….. This would add to mushrooming vs fragmentation.

Copper bullet jackets are almost always gilding metal, which is technically brass since it's some part zinc. 95/5 is typical.

They're not my photos, but I do know that the bullet halves were heated to cleanly melt out the lead, rather than prise out the cores & risk damaging the jackets.

H4895 comfortably pushes the 77TMK to 2930 fps at the muzzle through my standard Tikka .223. Its still holding 1930 fps at 500 yards.
I wouldn't be comfortable squeezing any more out of it though.
What does your accuracy look like?

Great in my rifle
2206H (H4895) will become available first quarter next year after a long production pause due to it being reformulated

Does anyone have a lead on factory BH 77gr TMK? I - uh - burned through my stash faster than I could resupply. Got hooked on the stuff and told myself I could quit whenever I wanted to, it wasn't hurting anyone and it wasn't *really* a problem. Now my life is in shambles and I've even considered selling feet pics, but thought I'd do the rational thing like ask for help before I lost myself completely.

For shame.
