Thank you and I ordered so 750degree paint today for the future. This is all Hornady brass so I’m trying to get everything right before I use high dollar brass
Educate yourself on proper temperature of cartridge brass , partial annealing or ductility restoration is what's to be accomplished .
One needs more heat ,nearer 1200-1300 Deg. F. for a shorter duration , in order to make your case neck and shoulder malleable .
No one's brass is annealed or realigning lattice aka crystalline structure growth ,not even at the factory level .

Annealing experiments were conducted on a number of the cold worked specimens. Figures 5a and b show color etched images of the specimens cold reduced 50% and then annealed 30 minutes at 500 and 700°F. No difference in the microstructure is seen in the specimen held 30 minutes at 500°F while a very small amount of recrystallization is observed in the specimen held 30 minutes at 700°F.
Figures 6a and b show color images of 50% cold reduced specimens held for 4 and 8 minutes at 800°F while Figures 6c and d show 50% cold reduced specimens held 15 and 30 minutes at 800°F. No change is observed after 4 minutes at 800°F, while a minor amount of recrystallization has occurred after 8 minutes.
Holding specimens for 15 and 30 minutes at 800°F revealed partial recrystallization after 15 minutes and full recrystallization after 30 minutes. The grain structure is relatively fine but is not uniform in its distribution.
WON'T make any difference what any of these people tell You or I tell You , simply READ and You'll fully understand WHY lower temperature DOESN'T do a damn thing . Higher heat shorter time ,lower heat WAY WAY TOO LONG OF TIME ,you'll ruin the case as heat will migrate through the cartridge case body and screw up the base . Persons who run cases at 700-800-900 Deg. F. , aren't doing anything but amusing themselves . Not a single one of them have an HV gauge ,so they DON'T know and only guess or pass the lie they've heard along .
