I picked up a used LR mauser barrel in .280 rem and 7x64 brenneke for the cost of shipping. I thought it was a great deal until I looked at the bore of the .280. Rifling is nearly shot smooth, a little bit of pitting and what might be a bulge. Is it worth using for a PP barrel or should I just toss it.
The 7x64 is in great shape. This will be used in a receiver I picked up.
