Seating gone crazy hard

[Average joe]

Did you tumble with stainless pins?
This has caused me problems in past.

Ok. Got wierd stuff happening ..
Same Brass ive shot in rifle ,Same projectile ,Same seating depth , Same fl bush die ,( wilson ) , Same size bush , Same annealing method , & projectiles have allways seated smooth ,& easy . .
Now all sudden i have Very hard seating pressure . .
Only thing ive done different is tumble brass Then anneal . Has this stuffed my brass. I usualy never tumble clean.
Neck all measure same as before after firing & After sizing .
Has me stumped .
Has All the brass just failed at same time .which is vey hard to believe

Tumbled how? If pins, that is your issue

I have no clue who come up with the idea to use ss pins and ultrasonic cleaning but it should have Big Red Letters all over it

Only corn cob media. I would never use pins .

No mate . Only used corn cob media .

.....but check that bushing again. Somebody might be playing tricks on you.
Ticked off the misses lately? Got a kid in the house?

Lol. All good there mate . . .

Yup! I’m a devoted corn cob guy. Sometimes walnut shell if it’s on sale.

Ok. Update.
Ive champered case necks . Checked dies. Resized cases after shooting off thosethat where bad . STILL very hard seating. , So ive bagged em up ready for scrap heap.
Pulled out some other adi cases & run thru same die & seated same bullets &, they are Easy to seat back to normal .
So its not my dies . Its Defintly the cases after tumbling . .
So im just going to move on & put it down to ,, tumbing . Going back to my original way that had No tumbling .
Thanks for help . . My 1st time here &, irs a great forum .

Try it again!…. Chamfer,…. Run a nylon brush that fits snug in the neck in and out 2 or 3 times but pick one and do it the same and try seating another bullet! If that don’t work do the same two things and put some graphite in the necks I guarantee the brass isn’t ruined

First time I ever heard an Aussie quit because it’s “hard”!
Don’t give up! Try annealing them again......a little longer.

 

[bozo699]

All that happened there was some Cobb residue left in the necks and when you annealed it flashed and you have a glaze of shit in there!… brass is hard to come by right now if you throw it away throw it to a friend that can use it.

I couldn’t agree more. Why knock off the natural carbon lube left behind after firing. If you do decide to use SS pins, I suggest using imperial graphite lube and finishing seating to depth less than 24 hours before shooting. Otherwise, the velocities seem to be all over the map.

I got the bright idea to clean the inside of my necks with 0000 steel wool one time!…. It was so shiny you could read a newspaper in the reflection!… I loaded up 100 for each gun , light heavy and 11lb and headed for Deepcreek in Missoula Montana, I loaded them long so do a little testing at the match!.. about 2 weeks had passed since I had loaded them first match I got my range box out set up my K&M and it was all I could do to move them and when they did move it was a loud pop!…cold welded themselves!…… shot horrible!…up all night in a motel room pulling bullets dumping powder putting graphite in the neck and reloading them for Sunday’s match……lesson learned!…..

Yep mate. I allways champer necks & clean inside necks with brush . .

Do you...
* Tumble
* Anneal
* Resize
In that order?

 

[Straightshooter1]

Because annealing leaves such an oxidized coating of the surface (and that coating can have remnants of what was used to clean), I always anneal before cleaning. The cleaning afterwards (still leaving carbon coating in the neck), makes for easier seating than if nothing is done to the neck interior after annealing.

Lube !

Ive put it away . Will try again . Just not yet as im trying to load up for the boy to do his match on weekend. After that i will re anneal & see how seating goes .
