Have a new barrel in .223. Fired 100 times, went to neck size the 100 brass.
Backed off fl die 1/4 turn, sized body. Backed off die 1/2 turn it sized the body.
Turned the die 1 full turn from shellholder. it still sized the body.
This is a new, name brand barrel. Have neck sized much brass with these same dies
This only happens with brass from this barrel. Do I have an oversize chamber?

Didn't want to say, but yes it's a Mcgowen.
I neck size with neck sizing dies. I've never tried to neck size with a FL die. You can just add a neck die to your existing die set cheaply enough.

Just curious, could you put a caliper on the once fired brass and tell me how much they "growed" ?
Measure your brass and if it is out of speck call McGowen, he stated on here that he will take care of his barrels.
Aint it lovely when someone start's a thread then leave's it :-\
The guy may just be at work you know. Some folks have to work on Mondays...

1st- Don't normally neck size. Was trying anything to make this barrel shoot.
2nd-My sized brass measures .374 just above web .350 at body shoulder junction.
brass shot in Mcgowen .380 just above web .355 at body shoulder junction
Contacted Mogowen they said send barrel back + fired brass And my dies.
There not getting my dies' but I will send sized brass from dies.
I had 2 H&R Handi's that "grew" brass like that. Brass wouldn't last long shooting from that barrel. Thank's for the measurement.
Buy a neck die.
Buying a neck sizing die won't fix the problem, it will just hide it.
I load for 4 different .223 and just like to be able to grab a box of
re sized brass and load. Like I said don't normally neck size' just trying
to make this barrel shoot decent. It doesn't shoot as good as the old
factory barrel I pulled off.
If your fired brass has stretched .006" just above the web area (start with new brass), that barrel needs to go back. You're gonna end up with a case head separation if you don't watch those cases like a hawk....
Be safe and have McGowen fix it.
The barrel is going back to McGowen.
Just hope it's not within their specs.
Some thing is just not right with this barrel.
This is what is so frustrating for me. The McGowan barrel shoots worse groups than the factory barrel taken off the gun, which I have no idea how many rounds have been shot through it. I also bought a .223 blued, fluted from Northland for (by the way, Thirty06 is my father-in-law) my Father-in-law and this barrel will out shoot this "high dollar" barrel all day long.Originally Posted by thirty06
By the way, Jim has contacted McGowan and gone to bat for us on this concern, and I just wanted to mention how much I appreciate Jim and all his hard work!!!!
Something is not right! I am looking at the SAMMI chamber specs for .223 Rem. and the maximum diameter .200 ahead of the head is .3789.
Sounds like some reamer chatter/wobble allowing it to cut oversize.
Just my $.02

Barrel is sent back. Now just wait and see what they say.
When I pulled the barrel I stuck a empty case in backwords
it went in over 1/4 in. Wouldn't go in the factory barrel at all.
I'm a dumb hillbilly, but that just don't make sense to me. How could a barrel like that get out the door ???
Possum I'm with you.
Now just wait and see what they say.
Good new's is I guess they'll take care of you.
They said they'd take care of it, unless it's within there spec's.
Update, no word back on barrel yet.
But they did send 200 brand new brass to replace what
had been shot in barrel. Makes me think must have been
a problem and they are fixing it. Will keep updating.
Got the barrel back, here is the link to the update in customer feedback. ;D

Funny you mentioned that.... I went through that with McGowen myself. They said for a 1:12 .243 you can use up to 85 grain bullets. And then He stated to use a 85 grain bullet, coz that's what his gunsmith told him. Dan doesn't handload. Then he refered me to a twist calculator, and that seemed to help. I was shooting 3 or 4 inches at 300 yds. I got a load with the twist calculator down to 1 inch at 300. But there's other varibles involved with another calculator, from JBM Ballistic on stability.

I'm 60 years old and the world I grew up in no longer exists, Remington firearms is now owned by a large International (French?) corporation, and Winchester now belongs to General Dynamics weapons division.
Our brass cartridge cases are being pushed to the side by Companies like Lapua when it comes to quality control standards. If you are looking for quality and uniformity in your cartridge cases then buy Lapua just as the bench rest shooters do. If you measure an American made case at the base web area and measure a Lapua case you will see that our American made case are on the small side of manufacturing limits.
On top of this European made firearms and ammo can differ greatly between the European CIP standards and American SAAMI standards.

On top of this you have plus and minus tolerances for chamber reamers, cartridge cases and reloading dies, your chamber is on the plus side, your reloading dies could be on the plus side contributing to your problem.
Also please note the first thing a bench rest shooter does if he is using off the shelf standard reloading dies is to remove the ball expander to reduce case neck misalignment.
If your are going for the utmost in accuracy you need custom dies, a custom chamber and good quality brass.

Below are two different manufactures of .303 British brass that have been fired once in the same Enfield, guess which one has a larger base diameter.
