Annealing
« on: February 28, 2011, 09:50:54 AM »
I guess because I'm chasing the elusive one hole group and wouldn't mind my brass lasting longer, I'm considering trying the annealing thing.  Read a lot about it, seen all the different methods, not going to spend $400 on an automated machine.  Probably just use a drill and something to hold the brass, might spring for the Hornady kit.  Not sure if I should use the tempilac or just watch for color change. I'm not going to mess with pistol brass as I can get it pretty cheap in 40 and 44 mag.  As of right now the rifles I reload for are the 204, 223, 7mm-08 and 300 RUM.

I do have a pile of reject brass that I could experiment on.

How many of you guys anneal your brass?  Is it worth the effort?  Do you see a benefit?  Do you use the tempilac? How often do you anneal?  Does it depend on the caliber? I don't run max loads but a couple of my calibers are pretty hot by design.  I also neck size with Lee Collet dies for the 204 and am testing with the 300 RUM.

Annealing is more for improving case life rather than improving accuracy.  Personally, until recently I never thought annealing was worth the trouble and I would probably never do it for the cartridges you mention.  Recently I bought some supposedly 378 Weatherby Magnum brass that someone had resized to 30-378 Weatherby Magnum.  Considering the price I got them for and the cost of 378 Weatherby Magnum brass, resizing will be worth it and with all that working of the brass, I'll have to anneal.  There is a case holder and drill attachment available from Lee Precision and I have the Tempilac for when I get started.  From what I've read, once you're used to doing it, you don't need the Tempilac.

This git's kicked around alot, there's ton's of advice and video's out there,
 There is a learning curve, I trashed a bunch 308 cases trying different ways and doing it wrong. I'd suggest finding a bunch of range pick-up or scrap brass to experiment with. I found Varmint Al's method and advice the best for me;

 Tried the tempilac stick and it didn't work well, you really can't get enough of the wax/stick on there to see it change, folks say the liquid works better.
 I wait for the dull red in a dark room and it works once you get the hang of it. Then look for the blue tints when finished for consistency. I guess the best advice I found was the blue colored neck should still shine, if it's lost it's shine you've gone too hot.
* clean/tumble the brass
* anneal
* dipping in water or air drying makes no differance, brass does not quench temper like steel.
* then size

 For me it's about neck tention and brass life, needs done after 3-4 firings. I can "feel" the button pulling hard through the neck and you can do the pliers test to the neck and find they are indeed getting "harder".
