Annealing

Pistol brass never (Does anybody actually anneal pistol brass!?), rifle brass every firing.

The general consensus for rifle brass annealing is, if you only anneal for your brass to last longer; every 2-3 firing's is fine. If you also anneal for accuracy; every firing.

I recently built a cheap annealer, and it only takes 3-4 minutes to anneal 100 pieces. If you're using a drill, It can become a pain to do it every firing.
 
I anneal because I'm a cheap A$$ and want my brass to last longer. So I'll do every 2-3 firings unless it's for Match grade stuff which is every loading. Pistol, never.

I have been thinking about annealing my 460 Mag brass. It's straight walled pistol brass but they cost over $1 each. Might be worth annealing to get more uses...

Thanks for posting.

Interesting results -

· Different brands of the same cartridge cases can require different annealing power settings due to differing case wall thickness in the neck and shoulder region. The greater the mass of brass to be annealed, the greater the power requirement. Lot to lot variation within the same brand can occur for the same reason.
· The bushing die used in this set of tensile bullet pull tests gave significantly more consistent results than the standard neck die with expander ball.
· Cases should be annealed every reload in order to get the best repeatability.

The bushing die gave better results because the Norma case necks were .0132 +-.0003 in thickness

Redding bushing dies come with a expander for people who do not turn their necks.

Meaning using a full length die with the expander and neck turning would give the same results.

I have Remington .223 cases with over .009 variation in neck thickness, and this would effect annealing and bullet grip.

Annealing rifle brass is to soften the neck area only...I would never anneal pistol brass as you could soften the entire case which would be a safety risk, so let’s get the idea of annealing pistol brass out of your head ASAP.

I anneal .308 every other firing (Lapua brass), but .300 Win Mag (Norma brass) and 50 BMG (mixed) every time...
