Annealing 6 ppc

[Sleepyhollow]

I know there is benefits from annealing that's a given but is there any on paper accuracy different ? At a match you can't anneal your brass you just shot endless your using new cases every match. I know in my 6 BR with Lapua brass I got 25- 28 loadings without annealing before the primer pockets craped out. Just wondering what the thoughts was with ppc.

 

[A j shooter]

I have shot ppc brass as many as 30 firings never annealed any .
And still shooting it. I don’t practice with new brass.
PS I don’t see any I’ll effects on accuracy. I use new brass for matches.

If your competitive with out it, do what your doing. If your not, then try it.

Annealing gives you more consistent neck tension and shoulder bump. I think it can keep your brass a little more competitive/consistent over the life of the brass.

Annealing (actually we're stress relieving) absolutely keeps case sizing and neck tension more consistent.

Good shootin' -Al

As usual, Bart is on top of things
I anneal and a lot of others I know do as well

The consistent shoulder bump Bart mentions is why i anneal with an AMP. my seating die indexes on the shoulder

Serious question...How can we anneal the shoulder area, which is thicker and has more mass, without over annealing the neck of the case, particularly with turned necks of say less than .009" thick?

Everything I've ever read on this subject says that if you don't get sufficient heat/time on an area, it does nothing to the brass but once you get to that magic point, the window of annealing vs over annealing is a narrow one. The brass is not as thick in the neck area..that's a given. So what gives? FWIW, I sectioned a ppc case and measured approximate thickness at the shoulder. It was right at .018, so a little over twice as thick as the neck tuned case for a .262 chamber.(.0085")

How does the math work on .268 necks? .0112. much closer.

Mike, that's a very important point.

I approach it from a stand point of stress relieving or as George Ulrich more correctly terms it: 'drawing back'. For example, with the 30BR cases (and others), there's a temp/time area that allows me to get everything I want for sizing and neck tension consistency while only treating the cases every 6-7 firings. This happens at a temp that's far below where most people work.

I don’t know nearly as much as others who have commented. But I did make an observation before my match the other day. I use an amp which supposedly does a perfect job. Normally first thing I do is anneal before resizing. Then when I seat the bullets on the 21 century hydro press and always notice the pressures vary a little. Did not think much of it. The other day I was in a rush, forgot to anneal. So I sized without annealing, and realized it. So I annealed after sizing this time, dumped my powder and went to seat bullets. I noticed my pressures were perfect case to case. Exactly 35psi. So my discovery and my point is annealing before sizing the case, my neck tension were not consistent and out of wack from just that little bit of work hardening.

Interesting. Since this was before your match how did your results compare . Better, worse, or about the same? Also, what is your neck wall thickness. That is a good bit more neck tension then I typically have with .0085 neckwalls and a .258 bushing in a .262 neck.

To be fair, this was a 200 yard score match, where the wind picked up mid day. So judging by that would be difficult. When I go back and practice some groups I’ll know more. If you try it, let me know what you think. I’ll let you know my bushing size later when I check, I do use a good amount of tension.

Love it! This is exactly why I anneal and probably picked up this little tidbit from Bart!

Tim: curious which seating die you use that indexes on the case shoulder? I think that’s a good idea but my seaters index on the case base.

It can be done properly provided you have a dual flame annealer. To orchestrate the process, put the tips of the flames on the shoulder wall junction set as close to brass that you can to quick anneal the shoulder before the damaging heat can travel up the neck and down the wall.

That particular piece of brass tells you the amount of time required in the flames to anneal correctly. Practice makes perfect!

I'm going to try this but see if you have done it before, after say 10-20 firings have you checked your AMP setting on the brass? I'm just wondering if it does. I checked some after 4 firings and there was no change at all.

I did check some after 10x the amp # was the same

I used the same 20 pieces of 6ppc brass this year without annealing.
I plan on getting 100 pieces fireformed and annealed got next year...
Then I can shoot both relays with newly annealed brass without useing the same piece 2 times.
Then go hone and deprime and anneal.

I think (no proof that has been peer reviewed) using thick unturned or “just cleaned up” necks helps a lot. When I was shooting a .262 neck compared to my .272 neck, my brass is extremely consistent after resizing. An additional benefit is thick necks can firmly hold on to bullets.
