I ordered 200 of them and they should be delivered this week. You are seein a little higher ES than I expected but SD is ok for $0.85 ammo. Look forward to shooting them and seeing what they will do for me.AAC 77gr TMKs from a 16" tikka. Still in stock at $0.85/ea. Every time I shoot a group, I end up wanting to buy more

If it doesn't have a value to input for tip length it's going to be wrong on every tipped bullet.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.


That's what I suspected, simply based on the logic of more information = a better output.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 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?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.
Copper bullet jackets are almost always gilding metal, which is technically brass since it's some part zinc. 95/5 is typical.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.

Waiting on them and sabers showing up Wednesday, if those tmk’s shoot well for me I’m going to try to get another 500, your report is encouragingAAC 77gr TMKs from a 16" tikka. Still in stock at $0.85/ea. Every time I shoot a group, I end up wanting to buy more

The one that pushes a 77grTMK in a .223 to 1800fps out to 675yds with an 18in Tikka.
H4895 comfortably pushes the 77TMK to 2930 fps at the muzzle through my standard Tikka .223. Its still holding 1930 fps at 500 yards.Lever, N540 are a couple options if chasing speed but yeah no way i'd chase that much speed..
What does your accuracy look like?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.
Great. Consistent around .75” or under for 5 shots. Depends on me mostly. H4895 (2206H) works best for me from 55 grn through to 80 with cup and cores’. I use BM2 or cfe223 for monos.What does your accuracy look like?
Reach out to @h2so4 . He is a black hills dealer and a Rokslide member. I bought a couple cases from him earlier this year. Good prices and good service.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.
