I went up today and did some experimenting. I have had nothing but trouble with cheap Wolf .223 ammo. The stuff is really loaded hot and can glue itself into the chamber. I tried a tiny bit of Imperial Die Wax and it all extracted perfectly. I found that it is not the chamber that is sticking, but it is the neck. This ammo also has a red sealant at the neck to make it waterproof, and I am not sure whether it is the sealant or the laquer/or both that is the problem. But just a tiny bit of Imperial fixes the problem. I also tried applying it to the chamber area of the case and did not see any difference. It was only necessary on the neck. Just a tiny little bit on the tip of your finger will very easily do 20 rounds. I meant to bring along some Bore Butter to try but forgot. This is such a revelation...Wolf is so cheap by the brick, it is hardly worth re-loading for the .223. The hollow points are extremely accurate, and awesome for even just punching paper. They make BIG holes in paper targets that are clearly visible at 100 yds with a scope or binocs.
