So, I'm on my third go around on my present batch of casings. Is it still worth the effort to anneal my brass at this point?
If you are sizing and the bullets still hold tight you shouldn't have to anneal for 10mm. Time and effort it really isn't worth it but it does work to a point.
However I have seen some cases that spring back open after the resizing which can leave the bullets loose and can be pushed deeper after loading.

I have never bothered annealing short straightwall cases. They are relatively cheap. I average 11 reloads before they are lost or split. That puts my average brass cost at 1.5¢ per shot if I start with starline brass. I reload twice at full power and then relegate them to "practice" velocities of between 950-1200 fps with 180 grain. The slower recipes are for my kids or new shooters.

+1 I just load em til they won't properly hold the bullet or they split like sqlbullet does. I only use them for plinking loads which run around 900-1000 fps. There is kind of a built in safety factor in this approach too. If you do get a set back bullet, at least you are only firing a light load with increased pressure because of the set back bullet as opposed to a maximum load with increased pressure as a result of the set back bullet.
Put another way, if things go sideways, you only lose an eye as opposed to losing an eye, two fingers and a nipple! :D
