Some .307 bullets

are designed for the .30-30 cartridge. I don't know of any other cartridge that calls for them, and a lot of folks load .308 bullets in the .30-30. You could load .307 bullets in cartidges designed for .308 bullets, but it isn't clear what accuracy would be. And, bullets designed for deer at .30-30 velocities would act more like bullets designed for varmints if loaded to .300 Winchester Magnum velocities.

I personally would not substitute the .307 for the .308 or vice versa. Pressures using the larger bullet in a barrel designed for the smaller bullet will be higher. How much I don't know. Using the .307 in a .308 barrel would likely be safe but I suspect accuracy won't be good.

307 Winchester
From Wikipedia, the free encyclopedia

The 307 Winchester cartridge was introduced by Winchester in 1982 to meet the demand of .300 Savage performance in a lever-action rifle equipped with a tubular magazine. It is basically a rimmed version of the .308 Winchester cartridge with thicker case walls.

The Winchester Model 94 Angle Eject rifle was the only rifle produced to fire the cartridge, though Marlin created some prototype model 336 rifles chambered in .307 Win. It is still loaded today, but many handload to gain better performance and accuracy. It is recommended that only flat-nosed bullets be used.

The .307 Winchester cartridge sees today widespread use especially between sporting shooters in Spain, whose gun laws consider the .308 Winchester as equivalent to the 7.62x51mm NATO and thus ban it from civilian availability as a "military caliber".
That's probably what you have found. Measure those bullets, I bet they're .308. Are they flat points or a very blunt round nose?

SL1 is right.
They are probably old stock, I don't think anybody bothers to make .307" bullets just for .30-30 any more. They will work in a .308 or other .30 caliber. No way to know how accurate they will be except to shoot some.

Yes, that is what I am saying.
What brand are they, Sierra? That is the only bulletmaker I know of to bother to make .30-30 bullets to a different diameter, everybody else just goes to .308... including Winchester. And Sierra does not any more.
