Dear Lew, the old standby, 70/30 Cu-Zn, still applies to nearly all brass for cartridge manufacture over all calibres…some heavy duty (Cannon type) brass will go to 72/28 ( different "springiness) and the older (German) 67/33 is still in use for a lot of Rifle cartridge brass.
If one looks at Milspec (USA) brass, the Major commercial makers, which do both Commercial and Military orders, will most probably stick to the one specification ( ie, by default, Milspec). This ensures consistency and economy of brass mill production, and interchangeability of “Military” Brass into Civilian sales ( ie, “job over-runs”).
As to the Pistol brass, due to the lesser number of “draws” required, there is also less annealing required.
Normal annealing is done at “Punch & Cup” stage, and then (if necessary) before Heading/Bunting/Primer Pocket final Form stage.
No final anneal is required on cylindrical cases (most Pistol calibres,) and those rare Bottle-necked Pistol calibres don’t need any anneal either after necking…not like Rifle cases.
Remember, Military (pistol) cases are meant to be “once use”…I think the same procedure would apply to Starline whose primary purpose is the supply of “Reloadable” cases, and in Pistol straight cases, a Neck anneal is not required ( case necks are still soft from the Pre-Bunt anneal.)
Annealing of Pistol cases ( whole Body) is necessarily carried out the rotating mesh cylinders in a furnace, followed by dumping in cold water and an acid pickle to remove scale, before further forming etc.
Differential annealing ( Rifle cases) necessitates specific machinery, to keep the Workhardened head unaffected by Neck and shoulder annealing.
I think full specs may be available from the major makers if one requires a quote for several million rounds…But otherwise, I would say, on the basis of Industrial and Commercial economics, the MilSpec requirements are pretty close to the mark at least where US production is concerned ( or any other Country supplying to US Milspec standard.).
The European (CIP) standards ( and NATO-Spec) would be similar if not identical.
