I agree. Most of my ammo shows the same thing after I fire it in my Krags. Don't hot rod the ammo and keep an eye on your case prep and loading procedures.

Yep... I concur also, perfectly normal! Never try to exceed established loads or acceptable pressures (like trying to get 30-06 velocities out of her), and you should be find and dandy!
Re: .30-40 brass above the rim slightly expanded/bulge
Only thing to watch is how much you are sizing the case, if your dies are minimal dimension full length sizing is needlessly working down that bulged area and can cause a lot of work hardening and speed the failure rate of the brass. IIRC the Lee whack a mole set only neck sizes so won't matter, but if using a FL die set you can back it off to only neck size or minimally size the brass (if used in the same rifle) and this will extend case life. Given how hard 30/40 brass is to find you might want to Google "case neck annealing".

Looks normal to me. Chamber sizes varied some, and the ammo makers have pared a few thousandths off the head diameter over the years. With a new case laying in the bottom of the chamber, they sometimes expand a bit more on the top
