Annealing brass

[youp50]

Is it worth the effort?

[Richard]

It is if you are trying to get the most life out of your brass? Also if you want to keep neck tension the same. Probably for a general run of the mill whitetail deer hunter, its not worth the effort. If you are a target shooter and buy high quality brass (i.e. Lapua @ arund $90 for a 100 pc.............6mmBR). #1, you want it to last and #2, you want even neck tension each and every shot. Particularly if you are in the long range game where velocity and Extreme Spread is critical to vertical impacts.
When I was shooting my 6.5 x .284 improved in 1,000 yd. BR, I annealed before every reloading. With my BR brass I go about 4 firings before annealing. With tight chambers, bushing dies, keeping headspace to almost zero (preventing case stretching) you should easily get 25 to 30 loadings on a case. I once had a set of 6mmPPC Lapua cases in a fitted chamber that had a recorded 93 loadings on them.

When making custom brass annealing is a must or you end up with split cases but for the average shooter annealing most likely will never be needed. As Richard said the tighter the chamber the less annealing is needed. Mike

Even with new brass, I have always resized, especially the cheaper
stuff. Not to pick on Remington because any brass can be inferior
to other brass in a different lot, there were two rounds which cracked
on the first firing. This was out of the first 20 of a 50 count package
of .25-06 cases. I then annealed the 18 good cases along with the
rest of the new cases in that package. No more problems.

Have been annealing even new brass ever since. Richard is certainly
correct in that it uniforms case neck tension. One can feel the
difference when seating the bullets. The only exception to this is
some PRVI brass that I just started using. It comes new almost
too soft. The .243 is shooting GREAT with it, though.
