If they look good, I reload them and hunt with them.
Six months ago, I bought a mixed batch of reloaded 7x57, maybe 160 rounds.
I pulled them all weighed and identified the bullets as well as the powders, inspected the cases and then loaded up 2 boxes, cleaned, sized and primed the rest of the brass. I probably threw out less than 5% of the bullets and about a third of the brass.
Fortunately, the person that reloaded these liked Speer and Sierra bullets so identifying them wasn't much of a problem.
But the boxes must have gotten dropped and mixed up.
They were all mixed in boxes, even though each box was marked with load data.
A collet puller die works well for me.
