swapping brass between barrels

Jerry, isn't FL sizing every time also to make all the brass as consistent as possible? Does anyone, not competition BR, just neck size anymore?
It is actually a frigging curse; not meant to make the rest of the world feel inadequate. One cannot imagine the level of detail, scrutiny and accountability that is involved. It is almost akin to a cult and I'm in need of deprogramming.Actually it was a fascinating industry with some very highly skilled people with interesting stories and backgrounds.
Chino.
I understand. Worked for an OEM, in that field.....And it's a little hard to adjust.
I have known 3 guys, who mixed brass....and all 3 broke off the bolt handle trying to open the action....Don't know the specs....
I have had 3 rifles. 3 very different rifles. But, all barrels were chambered by the same guy...Maybe the same reamer.....prolly 10 yrs apart...
3 rifles and maybe 10 barrels.....and I got adventurist one summer.... 6 boxes of brass, sat there looking me in the face......
Heck, so I tried them out. They were pretty old brass.....
The only problem was sticky brass on opening.....
I sold one of the rifles. And am down to 3 boxes of brass.
NOW A BIG NOTE. I was shooting these brass at "local score matches".....
Group NBRSA Tournaments. I use very new brass. 2 Tournaments and they become score brass. 20 pcs. at a time.....
I am trying to win my second Group Tournament... and maybe some Eastern Region HOF points......ER NBRSA is tough to win in.....
Yep.
A "Yard Bird" who wants a day off, can destroy a 688 boat.
Some jerk off started a fire in his vacuum cleaner. He got a lot of days off.
"On 1 March 2012 Miami pulled into the Portsmouth Naval Shipyard in Kittery, Maine for a scheduled 20-month Engineered Overhaul (EOH) and system upgrades. A civilian employee started a fire aboard the boat on 23 May 2012. It impacted the forward compartment of the submarine which includes crew living, command and control spaces and torpedo room. The revised estimate to restore Miami increased to approximately $450 million with completion estimated on 30 April 2015. A further damage assessment found that more extensive repairs and fire damaged equipment replacement were necessary, which raised the expected cost from $450 million to $700 million. Due to budget cuts, it was announced 6 August 2013 that the vessel would not be repaired and placed on the inactive list.[1] On 28 March 2014, Miami was formally decommissioned.[2]"

"On 15 March 2013 Fury was sentenced to over 17 years in federal prison and ordered to pay $400 million in restitution.[14]"
The best Prison sentence of an offender ever....
Yep.
Not picking......
I just ran across an vid about all those windmills. They only last 15-20 yrs........WTF....???!!!!
They produce less power, than it takes, to make them and they are all SH*T after a few yrs.....We used to make cars that lasted longer....I see trucks hauling salt that are older than me.....
WTF!
It's neck size and FL size.....
Some guys under size. With a duel port. Quick in and quick out.....200 y and consistent wind, shoot has fast as you can....
I call it the Joe Krupa method. Or the Wayne Campbell method. Of winning at 200y. Wayne waits till the last 2 minutes to shoot.....
I have tried it....shooting as fast as you can. It mostly works...But, when everyone is shooting as fast as you can............it's always nice to see all bullets touching....
Joe and Wayne seemed to have smaller groups........
nope, nope nope ya' got's that all wrong...... they're PROJECTED TO LAST 15-20yrs. In reality they don't often make it past 10, and often don't make 5yrs.
Can you spell BOON?
and DOGGLE???
These bad boys MIGHT be worse than corn fuel.... I'm just too lazy to compare. And if I feel the need to get fired up, I just have to look downriver to my old sturgeon fishing hole in Kalama WA where the Green New Feelies are spending 10 BILLION of your dollars on "something" that's been sold as a "methanol/ethanol plant slash/refuse/garbage converter thingamajig.... I've actually watched the local papers, read the signs and spoken with folks involved as this thing has evolved over the last 8yrs. Freakin' AMAZING how people refuse to think.
PT Barnum is being proven wrong too..... it's getting on to where you'se can fool most of the people most of the time.
"We the peeple" vote for this stuff
I'm finding more and more that this is one of the reasons I'm so drawn to guns, shooting and extreme accuracy.
I AM THE DE-LIAR in this neck of the woods. Ten tons of concrete to shoot from in a controlled environment with a machine shop and reloading room just steps away. Bring it on over and show me. We can settle this arg'ement and have fun doing it. Unlike billion dollar politics and policies, around here we can TEST stuff. Ain't nobody in it for the money. (not to say it ain't a skunkworks..... we got production lines waiting by for The Big Idea
)You think bullets go to sleep???? Well then come on over... we'll pop some over the air target.
You think you got a better way to hit stuff at 600yds???..... let' build it!
You think you got a quarter minnit huntin' gun???..... bring it.
You think that muzzle brake is better....... put 'er on the sled
You want to shoot a real gun? ..... COME ON OVER!!
Keeps my mind off them stupid windmills!!
LOL

Maybe some help
From my experience( very limited), It seems if a tapered chamber( like a 6ppc) is head spaced go+0 then the brass from that chamber will function well in other go+0 chambers. Should a gunsmith headspace a chamber go +.002 or .003 or.004( not uncommon)even with the same reamer, the fired brass from that chamber(multiple firings and mimimal resizing) would "click at the top" in a go+0 chamber, being as the major diameter of the longer than normal case was never sized fully in the standard length re-sizing die.
Other factors like chamber run out and the effects of polishing or not polishing the interior of the chamber come into play, but using 4 or 5 different ppc chamber reamers in my " el cheapo" Grizzly lathe, all of my brass is interchangeable through multiple firings and different barrels.
Same problems occur when guys fire form initially with a full "wham-o" powerhouse load in a go + chamber.
If you take it easy with your first fire form in a go+0 chamber you should have no problems moving that brass to other barrels.

Are you using Gordie Gritters' method on your Grizzly?
Al,
I'm not sure how Gordy chambers barrels. I didn't want to spend the 50 bucks for the video. My friend and shooting buddy Andy Laidlaw from north of the border got me started about 6 years ago. I don't know where he picked it up but I would bet he didn't part with the $66.50 Canadian.
In a nutshell, rough cut the shoulder and tenon, bore and ream the chamber, thread and make final headspace with a finish shoulder cut, cut the cone, done.
Easy to nail the headspace with that last .002-.005 shoulder cut.

Al.
We used a term back in the before time. SAME SAME....By the way. Duct time.........
Last told. There are 4 different 6PPC reamers.
Then there is the Dwight Scott reamer......And that was 10 yrs ago.....
That sounds familiar.....Randy maybe....?????? Or can't remember his name.....Red Dixie cup.....

When you spoke of rocket science and their mentality. A friend of mine was an engineer at NASA and sent a letter to the top dogs before a space shuttle launch. You'll recall which one as it blew up. The letter explained how the rubber o-ring would fail, which it did. No one paid attention.

It often take multiple firings for new brass to fill out the chamber completely.
And they generally need to be decent power loads and NOT reduced loads.
S^2 D^2.
Same Scat. Different Day.
It is not all that hard to keep the brass separate for each barrel.
I keep very tightly matched sets of around 100 shells together for Varmint shooting.
Down to the neck thickness run-out.
I measure with q 1/10,000 dial indicator and spin each shell.
Group them into batches that have around the same run-out.
I buy a large batch of commercial cases and start trimming.
Lightly chamfer ream inside and out.
Then weight variation.
Then neck thickness variation.
The group size from a batch of shells with <0.0003 neck thickness variation compared to <0.0006 thickness variation show up at around 400 yards or so on paper.
And with all this full length sizing you are slowly altering the temper (hardness) of the brass.
Mostly around the shoulder you are moving every time.
Using a 1/1,000 indicator to control reamer depth is hard enough to hit the same number over and over.
A 1/10,000 would be a nightmare.

Varmit Brass
Looks like you enjoy going through your process brickeye. To each their own. I find a load that works and shoot it. I find the wind is usually blowing and that evens the brass prep process. Never had a varmit complain. BTW, I don't tell the rifle either.
Enjoy
