I have the stuck case remover for just such an emergency. I was posted to the far side of the moon when I had my first stuck case. 30 cal and a Win casing. If you don't have the tools, you're hooped. I don't get that problem now, probably because I have the tool to fix it. You're quite right though, the two worst offenders seem to be 30-06 and .223. Long straight sides and not much rim. I was sure someone would bring this up though. I guess for his dents, if he just doesn't press so hard in the lube and just not quite so much...
