The core/jacket "separation" on the sides is due to the lead core being compressed in the fixture I held the bullet in to section it, while the jacket "sprang" back after the bullet was released from the fixture.

Very nice, thanks for doing that for us! I heard rumors the Golden Tiger was FMJBT which helped accuracy, but I guess this confirms it.

Wow. Thats a large void. Any chance you could do a second one to see if its consistent?

Does anybody know if there are any gel test out there for GT?

Interesting info.Thank you for sharing.
Would be interested in a gel test myself

Dropped by almost 60 full cases in the time it took me to submit my order! HURRY!!!! 132 left!

Still in stock.. it seems the Ammo crisis is slowly winding down, its been in stock for 13 minutes AND posted about online!

Getting back on topic, I'm looking for the same info as Toledo:
"Wow. Thats a large void. Any chance you could do a second one to see if its consistent?

Does anybody know if there are any gel test out there for GT?"

Also how capable would this round be then? Something effective on hogs, or is JSP required for that job? I ask because I heard of all the folks using .223 on hogs, while people seem to be leery of anything non-JSP in 7.62x39 on hogs.

Hoping someone bought me 1200 rounds to trade for my complete M4 lower. I still cannot believe noone has done this.

I have seen other GT rounds sectioned and my findings are identical. That was a lot of time with some sand-paper...

M-67 is flat based with no airspace. This is boat-tailed with airspace. Two different animals.

I've sectioned some of the earliest GT that was imported and it too has the boattail/airspace construction... So they seem to be consistent in construction to date.

You or anyone you know shot anything with it? Does it yaw very early?

My bad, I wasn't sure, been awhile since I was deep into 7.62x39. I knew the M43 (PS) was the steel core boat tail , Then when I read your post it came back to me the Yugo flat base solid lead M67 duh

An acquaintance of mine has agreed to test some of this round in gel for me as he is curious, as well, as to its performance. He is a busy individual, so we might have to wait for a while, but the data will be well worth it, as it will be conducted in a lab quality setting.

The center of gravity being to the rear of the projectile should cause it to tumble sooner than M-43, but it's longer length compared to M-67 should make it tumble later than M-67. I'd expect to see something inbetween M-43 and M-67...

I agree with the flat base part, but I understood that the M67 DID incorporate the aircavity much like the Soviet 5.45x39! It was the original M43 that did not have the cavity. If you google M67 you will find videos and reports of hogs being shot with them with good results. You also need to check out the hollow point's with the inside serations in the jacket, called the 8M3.

NOPE. The M-67 does not have an airspace. It tumbles because the center of gravity is to the rear as a result of it's flat based design. I have sectioned numerous M-67 and M-67 types and none of them have an airspace like the 7n6. Some M-67 or M-67 types have a very small airspace in the tip, like the size of the head of a pin, but this is not intentional nor does it have any effect on it's performance, it is simply a manufacturing artifact.

I have also sectioned many other Russian and other 7.62x39mm projectiles, including the 8m3. I do not beleive that the 8m3 was designed to meet a specific goal of lethality or anything else. I think the scoring is simply a result of manufacturing technique. I have other examples of various internal jacket configurations that suggest manufacturing intent, not performance.

What about the airspace in the GT? I take it it is a little bigger than the M-67 you have seen? Is it going to make much of a difference down range?

Always nice seeing another Vermonter here!

Back at ya Vermontah!!

There is essentially no airspace in the M-67. In the odd case that there is, it is a manufacturing artifact and not intentional. The airspace in the GT is huge by comparison, but the center of gravity is not as far back as the M-67 so performance (yaw) will be different.

would be very interesting to see a ballistic gel test between M43 M67 and the GT projectile

It tumbles at about the 4" mark. Not too shabby for a commercial load.
