I have approx 80 308-7.62x51 winchester match fmj from lapua,180 grain. I bought them from my local rfd approx 18 months ago. They look quite old judging by the packaging. When cleaning brass after firing i noticed a small split on the body approx 4mm up from the head of brass. Bit of a shame because they performed reasonably well in my gun. Can i reuse the bullets if i strip them out, they are quite old. Are there any issues in reusing the bullets. They are the d46 bullet, which means very little to me due to lack of experience. What has caused the small split in the body? Thanks.
