You can sink de-primed cases in a pie pan full of water up to the shoulders. Just a second or two with a propane torch to change color to silver will anneal even case necks old and previously fired.
Younger cases can be inside neck lubed a little then simply run through the .355 sizer. I like to do it in two runs, half then all the way through. If you have it, an intermediate .338 expander ball (screws right on your existing de-cap rod in place of the .355") would be even better. Then the .358". Just load those and fire form.
For fireforming via "blanks" I have had outstanding luck with faster ball or small grain powders like AA#7. Bullseye and Unique too but the small/ball AA#7 has less air space between granules and just seems to do better for me.
Great pics.

.30-30 is pretty to open up to .35 with one pass
