for 10k rounds of anything:
1. Rifle was shot to 10,000 rounds
2. No throat erosion was detected.
3. No rifling wear was detected.
4. No gas port distortion was detected.
Saying these bullets caused no more, or less, wear than standard designs would be one thing, but some of the wear in those areas comes from propellant gas, and I'm not sure how a less-wearing bullet would prevent that.
