Last year was my first experience with cold weld. I had some 06 loads from a couple of years back. It's a load I've used a lot in the past. But I had a couple of shots where there was difficult bolt extraction. I stopped immediately and then seated the other loaded rounds deeper. There was an audible pop/crack. I reseated the bullets again and had NO problems.I normally don't clean inside necks 'other' than swab lightly with a clean Q tip.

If you're interested enuff you might search cold weld here in Ask the Gunwriters or in Hunting Rifle forum. Good luck.

. I will do some research on line. I'm going to dig out my books on metallurgy from college and look at brass and copper composition! Just seems strange that it only happens randomly! I'm going to take a larger sample base and see if that changes the statistics I've seen.
