Skip an annealing?

[Jeff Porter]

I have a batch of Lapua 6 BR now 6 BRA on its fourth firing. I have annealed it the other three cycles but may be in a bind where I need to load some brass before I can anneal it. Will I see any noticeable difference on paper if I do not anneal this cycle?

I run Berger 105 Hybrids with H4895 about 2900 fps and it is typically at 0.3- 0.6 MOA load in my rifle.

I am a sling shooter shooting at the big midrange target at 600 yards. My gut says I will not see a huge change in this case.

I used to run Service rifle brass 5-8 reloads and never annealed the .223 stuff and shot HM scores.

I feel I am a above average shooter. I just shot 100 Lapua 6.5 CM that I missed annealing for the first time after 7 cycles.
I couldn't blame any misses at 1000 yards because they missed an annealing. Maybe 100 cases wasn't enough for a sample study.....

I wouldn’t worry about it at all, just load and shoot, it may very well shoot better.

If the annealing you've been doing has been done properly, missing a a cycle as you're described won't make a difference that you can see on paper. In general, it takes ~3 or more cycles before one might actually see a difference, even at 600 yards. Other factors are involved, like chamber and sizing die dimension, that can reduce any noticeable changes on paper with regards to annealing. Missing a single cycle, you aren't likely going to feel any difference is seating either, though the AMP seating press might be able to show a small difference.

I don’t notice missing an annealing every now and then at all even at 1K. Don’t worry about it.

 

[Bob3700]

I anneal after three firings on all my brass. Have not seen a difference in seating pressure or impact on target even at 1 K.

Don't sweat it. I skip a round of annealing on my 6BR every now and then and see no effect on velocity / ES / SD / performance on target out to 600. i shoot 6BR / Lapua 105 / N150 at ~2900.

As long as you’re not over working your necks you should be fine.

 

[marchx]

in my case 4 times fired brass, even if annealed every time will shoot bigger groups than fresh brass. I know it's contrary to popular belief, but as Erik Cortina righlty pointed out: believe the target.

My understanding was that you anneal brass to give it a longer life, nothing to do with accuracy.

 

[rijndael]

nothing to do with accuracy.

AMP has some datapoints that says it impacts accuracy too.

I know that AMP annealing closed up my SD.

Over not annealing or flame?

 

[misser]

I know that AMP annealing closed up my SD.

because you were over doing the flame annealing?

No. Never annealed before AMP. I just wanted to point that out before some asked about the method. Lol

Not annealing
