Got my Endevour in yesterday and cleaned the bore and breech. I did not buy any anti-seize so I used some bullet lube that came with my Lyman lubrisizer that I use to lube and size my lead bullets for my Sharps. I have not used that lube on any bullets as it is pretty stiff. It is moly based and holds up well to temp. I put some on both sides of the breech plug and worked the plug in and out a few times to distribute the lube. Do you think that using this will cause any problems. I guess time will tell.
