I don't know the properties of the lubricants you are using when the solvents evaporate but every time I try to lubricate any part of the bolt internals I have problems. If anything I would completely clean the inside and remove any gunk to eliminate any sluggish firing pin travel. Again, I have not studied your particular lubricant's but I have plenty of others. That has been not only my experience but many others. A dry film may be a good option.
