I use to have a friend
who shot every weekend he could at his private club and who kept meticulous records of each round he shot on a laptop, along with his component inventory, etc. He opined that he found his best accuracy from the second firing of annealed cases. Unfortunately he passed a few years ago so he can't chime in here. He said accuracy declined slowly after the second firing. I know from my experience, one can feel some cases starting to stiffen after the second and to steadily stiffen as the number of loads increase. I have tried to have mine annealed after 6 firings but that's an arbitrary number. Some cases work harden faster than others it seems.
The issue, if my old friend was correct, is that first firing after annealing

And THIS..... in a nutshell, is why I think annealing is silly. Getting one good shot out of 3-4 just doesn't make any sense to me!
Get 'em hard, fast as possible...... KEEP 'em hard and learn to tune 'em hard.
That way every shot is worthy.
Makes ya wonder why there isn't a chapter in Boyer's book about annealing...

I wouldn't be surprised
if he uses new brass for each and every match. Some consider it the cost of doing business. I guess that's fine if one can afford it. Like they say, if you can't run with the Big Dogs,don't get off the porch.

Not for competition but for varmint hunting, yes.
I push my brass 'wayyyy harder than they did back in the 70's-80's "fitted neck" days. I do have to resize every firing and I do keep a skosche more neck clearance on the FB rigs. 6MM and 30. My VLD stuff the bullets are very tight to get back in using fingers so they will shoot "fitted neck" but I still resize them too.
I have done pretty good annealing every time, Shot this brass over a 100 firings and it set records and placed well at the nationals with it. I turn necks three times with the same setting and once a year after that. Only way I retire brass is to dents on the case mouth and thinning a .0001 under what I turned to. Uniform neck tension is everything at long range and this is what I look for, Force indicators give this, and it shows up at 1000, in reduced vertical..... jim
in 43 yrs I could not blame looser case on vertical at 100 and 200 yds look at holding rear bag bill brawand
It is funny, you make a statement like that and you can not back it up with proof. They made fun of the many things I did at the super shoot the year I set 4 agg. records and now many are doing things like did . I remember you guys said measuring powder by volume was more accurate than by weighing it. You weigh cases though, with so many discrepancies on the outside to make that worthless. May want to look into weighing primers..... jim
I’m not at jim1k level, but I full length size, turn necks (usually around .0125”) with a setup on my lathe then anneal (salt) before tumbling. I anneal every time but only neck turn once. Also check case length to see if they need trimmed. I play the long range prone game though, so this might not help you.
Can you please expand on your “turn necks with the same setting” comment?
Do you mean after each of the first three firings?
Thanks
I turn to fire form but I don't touch narthex neck shoulder area because that is where it head spaces off on a 6Br imp. after they are fired and trimmed after I size them with out a neck bushing. I made a die to size the neck down to the shoulder, then expand it up to fit the Pumpkin mandrel and I turn down into the shoulder a little just catch your nail a little, it helps with the donuts. When they are fired again I will turn them again and the that get rid of the last high shots from the brass flowing around, then they are stay pretty good for the rest of the year. If you trim before you size, it will grow.... then I anneal and when I'm ready to use them I size the neck and body again, remember dwell time has a lot to do with sizing the same....... jim
Wow! Good explanation. Thanks
