3) brass thinning near the base.....VERY IMPORTANT to check for this or you will end up with case head separation. Its the result of brass flow from repeated reloading, and too much headspace, which is often because of setting your resize die up wrong.
Do a search on case head separation. Plenty on it and how to check for it.
