Please correct me if I'm wrong. The surplus 7.62x54R is all bimetal bullets, correct? And the Mosin barrel life is still great, right?
I see Wolf is importing bimetal 303, but don't want to cause undue wear on my enfields. If they were chrome lined, I'd have no worries, but they're not. TIA |

Can't believe all the mis-information about bimetal bullets. The steel used is so soft, that it is only slightly harder than the copper coating.
Y'all act like you are putting bullets made from steel files down the barrel. 
The US Ordnance Department did a test and found it is only a very slight increase in wear. You will likely never shoot enough to even notice, especially with a bolt action. |

You might be thinking of the Ball vs AP study. It found slightly increased wear from firing a steady AP diet. The Gilding Metal Clad Steel vs Copper study found little difference between the two. The throat would be eroded long before the rifling wore out. The US used GMCS bullets for years. |

Surplus 54r is not bimetal jacket. Surplus 54r is a copper jacket. There is a steel core. Between the steel core and the copper jacket is lead. They're kind of fun to cut apart and look at. What I cut apart was mainly steel jacketed .I don't recall any with a 3 layer bullet |

He's likely getting the information from this source: http://www.luckygunner.com/labs/brass-vs-steel-cased-ammo/ The conclusion here was that the bi-metal jackets on wolf ammo accounted for the increased wear of the barrels. You cannot deny that SOMETHING in the Russian ammo is eating these barrels faster than the American made federal ammo. The steel case would have zero effect on anything past the chamber, yet the entire barrel gets shot out, so clearly it has to be something with the bullet construction. |

I have NEVER seen seen steel cased '54R without a bimetal / steel jacket. Not saying its not out there, but it's not the norm. People would really be surprised at the amount of ammo that has bimetal jackets. The vast majority of M2 ball ammo has bimetal jackets. Lots of .30 Carbine ammo does too. Even a lot of USGI .308 has bimetal jackets. Winchester's basic .308 147gr bullets are bimetal. |

That source found the conclusion is was trying to conclude. A better, and more accurate test, would be to to fire the 10K of Federal vs 10K of Federal loaded with bi-metal bullets...everything the same except the bullet. Having different cases, bullets, powder and primers throws scientific method out the window. They didn't prove anything except different things are different. |

The powder is different as well... not a fair test unless you remove that variable. |
