Russian Bimetal Bullets and Barrel Wear – Is It Worth It?

Most Russian ammo is loaded with bimetal bullets which are mild steel jackets layered with copper with a lead core. The steel jackets are much softer than a rifle barrel but not as soft as copper. So it is a fact that these bimetal bullets do wear a rifle barrel faster than copper bullets as proven in the Lucky Gunner 10,000 round ammo torture test. It is a Proven Fact.

Wolf WPA 762x39 ammo

So we know that using Russian ammo like Wolf, Red Army Standard, Tulammo, Herter’s, Brown Bear, Golden Tiger, etc will cause a barrel to wear out faster than copper jacketed bullet ammo. How much faster? According to the ammo torture test performed by Lucky Gunner, the bimetal bullets wore out the rifling in a Bushmaster AR-15 rifle barrel after 6,000 rounds of rapid fire. The Federal copper jacketed ammo lasted over 10,000 rounds.

So lets look at what this means to the average shooter.

How long will it take you to shoot 6,000 rounds? 3 years? 5 years? It would take me 6 years to shoot 6,000 rounds through one of my guns. So I would need to replace the barrel or gun after 6 years. OK, I can live with that.

So what’s the total cost of using the Russian bimetal ammo?

Russian bimetal ammo (7.62×39) costs about $0.23/round when purchased in cases. The cheapest copper jacketed ammo (7.62×39) is Fiocchi at $0.45/round. The difference is $0.22 per round. So we multiple the cost difference times the number of rounds we’re going to shoot which is 6,000. That comes out to $1,380.00. So by using the cheap Russian or Ukraine ammo, I will save $1,380.00 but I burned out one AK-47 or AR-15 barrel. So I have $1,380.00 to do something with like replace the barrel or the entire gun and I have more than enough money to do just that. I only paid $497 for my Zastava AK-47.

So worrying about using bimetal bullets in your rifle for fear of faster wear may not be such a big issue. I know it’s not for me. I don’t mind buying a new rifle every 5 years with the money I saved in ammo. I really take care of the barrel with proper cleaning and a top notch lubricant (Froglube, M-Pro 7 CLP, AR4200 or CorrosionX), I may be able to stretch the barrel life to 10,000 rounds.

Just some food for thought…

Steel Cased BiMetal Bullets Vs Brass Cased and Copper Jacketed Bullets

OK…here we go. There’s lots of conversations about the steel cased Russian ammo being dirty, not accurate, wearing out barrels, unreliable, junk, poor quality, lacquer coating melting, etc.

Is this myth or truth?


Well there is a definite answer to these claims and Luckygunner performed a controlled 10,000 round torture test featuring 4 Bushmaster AR-15 rifles and 10,000 rounds of Wolf, Tulammo, Brown Bear and Federal 5.56/223 ammo.

Here’s the short version….the Russian steel cased ammo was not as reliable (but pretty darn reliable…9 failures (Brown Bear) out of 10,000 rounds) as the Federal brass cased 5.56 ammo in these firearms and did wear out the rifling in the barrels much faster (6,000 rounds vs 10,000+). The dirty and inaccurate claims are false as proven in this test. The Federal ammo was actually the dirtiest and hardest to clean.

Another false claim was regarding the lacquer coating melting in the chamber causing the case to stick. There was no such issue during this 10,000 round torture test. The barrels were very hot, up to 750 degrees and there were no signs of the lacquer coating melting or sticking.

If the Russian ammo manufacturers would use copper jackets instead of the bimetal (steel and copper) then it would be some really awesome stuff. I still plan on using Wolf, Brown Bear and Tulammo in my AK-47.

It would take several years for me to shoot 6,000 rounds plus I don’t shoot rapid fire where the barrel heats up to 700 degrees. This high temp kills barrels. I also clean my rifle after every 200 rounds or so. The torture test scheduled cleanings after 2,000 rounds. Plus…Froglube should increase the life to 10,000 rounds or so.

Herter’s 7.62×39 Ammo

I recently bought a Zastava N-PAP M70 AK-47 at Gunbroker and I’m waiting for it to ship to my FFL. In the mean time I thought it would be a good idea to buy some ammo. So off to Cabelas I go.

20141014 174732

I thought as big as Cabelas is they would have cases of 7.62×39 ammo and many brands right?


I think I saw 3 brands of 7.62×39 ammo….Herter’s, PPU and Hornady. That’s it!!! WTH?

PPU and Hornady were expensive for target shooting but may be good for hunting or self defense. I went back to the Herter’s shelf. I wasn’t sure who makes Herters 7.62×39 ammo but it was cheaper…$5.99 a box. Not knowing anything about this ammo, I only bought 1 box to try.

I also looked at 2 CIA WASR AK-47’s they had on display. They were pretty nice but $699. Way too much for a WASR. I bought a Zastava N-PAP M70 AK-47 for $467 on SWEET!

Anyway after I opened the box of Herter’s 7.62×39 ammo at home I discovered who makes it. The brass case has Tualmmo on it.

You can see the Tualmmo logo on the lower right.

20141014 174732

You can see it’s made in Russia if you look underneath the “20 Cartridges” on the right.

Tulammo is steel cased and Berdan primed with non-corrosive primers. The steel cases are polymer coated to prevent corrosion and assist with smooth feeding and easy extraction. The FMJ’s are bi-metal which is a layering of copper and soft steel. Regardless of what people say about bi-metal bullets, they are softer than rifle barrels and should not wear them out faster.

Tulammo is manufactured at the Tula Cartridge Works plant in Tula, Russia. They have been manufacturing ammo since 1880. It is one of the largest cartridge manufacturing plants in the world. The Russian military have been using ammo from Tula Cartridge Works for a long time in all their AK-47 rifles. That says a lot!!

I have read many articles and reviews on Tulammo. It appears to be really good ammo for AK-47 type rifles. It is very cheap too. I’ve seen it sell for about $0.21 per round or $219 for a case of 1,000 rounds.

I may run over to Cabelas and get 10 more boxes of Herter’s 7.62×39 ammo. That’s 200 rounds for $59.90 plus tax.

Expensive Defense Ammo – G2 Research RIP

I was browsing Gunbroker Ammunition, looking for some new ammo to review when I saw an ad for G2 Research RIP 40 S&W ammo.

G2 Research ammo


G2 ammo is way different from any other defensive ammo you will ever see. The bullet is uniquely constructed featuring a serrated nose. It is supposed to be devastating on soft tissue. I’ve seen gelatin and pumpkin tests and they looked spectacular.

Anyway, I wanted to get some and run it through my Glock 22 at the range for reliability and accuracy testing.

Well…..I halted my purchase when I saw the price. $147.00 for 2 boxes of 20 rounds. I’m not that excited about testing or using this ammo. If it performed over and above other ammo then I might consider it for home defense but there are other options that are proven effective in the field. Cutting Edge PHD ammo is just one that I really like and it performs extremely well. Lehigh Defense is another.

Multiple Projectile Ammo

We all know how effective the 12 gauge shotgun is with buck shot. 9 pellets hitting a target simultaneously is devastating. Shotguns are not as fast to draw into action as a handgun so… what if we could fire a multi-projectile round from a handgun?

Lehigh Defense multiple projectile 44mag

Here you go… Lehigh Defense .44 Mag multi-projectile defensive ammo.

5 projectiles fired at 800 fps. The pattern is effective out to about 35 feet which is typical self defense range. Penetration is from 6″ to a max of 12″. Over penetration is not a concern here.

Lehigh Defense Multiple Projectile ammo is available in .44 Mag, .44 Special, 45 Colt, 45-70 Gov’t and 458 Socom.
