Went to the range today and confirmed one of my suspicions. I have a group of brass that I had annealed before resizing.. This is brass that had previously been trimmed and sized from 223 Black Hills ammo and LC. It had been shot twice as 300.
I took brass that was annealed then sized/deprimed, then loaded. I also took brass from same group that had never been annealed and shot both...
Unannealed groups were horrible, annealed groups were 3/4 " and below.
I will anneal all my brass now ...
If you are chasing accuracy issues, don't overlook this.

Re: Discovery concerning annealed cases
so you are doing the annealing yourself? Can you describe the process that you are using...Thanks!

Re: Discovery concerning annealed cases
Basically using a torch, shell holder on a drill, dark room, ir thermometer, pan of water. Brass must be clean and shiny so you can see the color change. Do a few and check temp with ir thermometer. This will give you an idea of the seconds it takes. Basically a deep faint maroon... Hard to see it in a lit room.
If it glows orange....too hot...
Takes some practice. Honestly, I am seriously thinking about a Giraud. Take all the human error out of it and I can get the consistency I am after.

I use Tempilaq 750 degree http://www.amazon.com/Fahrenheit-Celsiu ... B0041YD47M
I paint in on several cases to get the timing down, then re check every 100 or so and adjust my timing as needed.
All the best...Bob.

Re: Discovery concerning annealed cases
how often are you annealing?
initial loading, each loading, or every 5-6 reloads like they say in the video above?

Re: Discovery concerning annealed cases
Still working on all the ones I annealed. My goal is 3-4. I have several hundred annealed.
Race season is here so my shooting will slow down...
