Help ID these bullets

[bobm]

I bought 50 of these yesterday not in the original box. I have no clue to the manufacturer. They are .338 dia. and weigh 230 grains, have thick outer copper jacket and moly coated. They have a steel inner core liner and are attracted to a magnet. Who made them?

Thanks, bobm.

They look like the OLD "Combined Technology" bullets. They had one that had a steel cup on the inside to stop any further mushrooming of the bullet for extreme penetration. The "Combined Technology" bullets were a collaboration between Winchester and another bullet manufacturer, whose name now escapes me.. I just looked it up>>>it was between Winchester and Nosler.. But I would not find YOUR bullets. Someone with better computer skills than I possess will find it for you..

They look like Barnes coated bullets. Matt

Hello Matt.. If you noticed in his description, they are attracted to a magnet. That's the steel cup inside the jacket. Barnes are solid copper or some copper alloy..

They might be the old "Combined Technology" bullets as ShootDots suggested. They were a joint venture with Winchester and Nosler way back. Attached is a pic of the ones that I have in 30 cal 180 grain.

I could not remember what they were called! "Partition Gold"! That's it! Thanks for helping me with my less than stellar memory!

That’s what they are Ben. I had some if these in 270 caliber. I remember the coating and the steel jacket over the rear core. I recognized them immediately...

Bob. Those are Combined Technology Fail Safe bullets. I have a bunch of those. Great bullet. They were the most complicated, toughest, and expensive bullet that was ever made. The front of the bullet was solid copper with a long hollow cavity. Then they placed an upside down steel cup then filled the cup with lead and plugged it with a tungsten cap. The outer coating is Lubalox which is Winchester's own developed coating. Unlike Moly, Lubalox will not build up on itself in a barrel.

Great info, Jim. Thanks.

Well, I may go to hell for this. But, I did it in the name of science, curiosity and visual entertainment for you guys. That was one tough nut to rough saw through then file smooth. I put a light touch of cold blue on it to highlight the hard to see steel core cup. The end cap looks to be crimped into place looking through my 7x B&L loupe.

That leaves me with enough bullets for 49 more elk.

Those are some killin machines right there. They dont shoot worth a flip but man they are deadly.
I think the first picture are worm weights though. No wonder they call them bullet weights

From my stash; 180 gr .308 dia, Fail Safe bullets. I agree that they are one of the more complex bullets ever constructed. The 10 that I fired through an Interarms Mark X in .30-06 were very accurate, but ultimately went with the 150 gr Partition Gold.
Was hoping to recover one of the FSs from backstop but they drill pretty deep.
