Today I had my first experience with breech plug lockup. I must have spent about 45 minutes trying to get my breech plug out. Are there any tricks I should know about???

I ended up placing my LRH straight on it's barrel and dripping Kroil oil down on the breech plug. After letting it sit for about 5 min, I was finally able to break it free with a lot of encouragement. Let's just say.....I came very close to reaching for my 4' long cheater bar. kl
