Was looking for 284 win brass I cant seem to find any. Read that I could use 6.5/284 but would need to "neck up the brass" what exactly does that mean and how do I do it? Was shooting this weekend, my Dad had some 284 ammo that he gave me with the rifle, the ammo was in a generic white box of 20 rounds stamped 284 probably 30 years old I think he picked them up at a gun show looked to me maybe someone selling reloads, on 4 rounds the neck separated about 1/8 " down and left a jagged edge on what was left of the case neck wondering what would cause that? Thanks
 
Dont shoot anymore of those dudes, thats from sizing. No telling how times its been reloaded, and its hard on your chamber and even worse could ruin you and your rifle.
Call Midway USA, Brownells, Hornady, etc. To find the brass you need..Nosler may have it too.
 
Like hooligan1 says, those are scrap. The cracks come from work hardening by repeated firing and resizing with no annealing.
You might salvage the 16 by annealing 'em. Using a regular propane torch, put the cases in a container with plain water up to the shoulder. Heat the case necks and shoulders until the brass changes colour and tip 'em over. Done. Red hot is too hot.
Winchester only loads .284 seasonally according to Midway. Appears that nobody else loads it. Or makes brass. Gun shows are your best bet.
Necking up or down is done with case forming dies or sometimes just running the case through a regular FL sizer die. Suspect necking the 6.5 up will need a case forming die. S'only 20 thou but that's a fair bit. And the cases will need annealing after too.
 
Go to midwestguntrader.com, and check the ammunition and reloafing page for Missouri. There's a fella that might have what you're looking for.;)
 
Given the events of the last several years, niche products have been increasingly hard, if not impossible, to find.

.284 is about as niche as it gets, unfortunately.

You will never know, the cause? There is a term called 'cold welding', I have never had a case neck weld to the bullet so I have to take someone's word for it. I have pulled down a lot of loaded ammo I did not load, I have crushed cases seating bullets, the plan was to loosen bullet hold, on the neck and sometimes on the shoulder there was the appearance of rotten brass, I have pulled bullets when the neck came off with the bullet. Something like unlike metals and electrolysis or someone loading with bad habits, the bad habit being cleaning cases with an acid and not removing it before loading.

I have .44 Mag round that Cold / Pressure Welded its self together.... no amount of pounding with the "Bullet puller" will separate the bullet from the case. As a matter of fact, the lead core of the 300gr XTP started to "flow" out from the HP, rather than the bullet jacket budging from the case.

Since this happened prior to the internet, it always was in the back of my mind "Why ?"

Since then, I have noticed some common factors in cold / pressure welding...

Both the bullets copper jacket and the nickel cases were squeaky clean... so there was nothing to act as a "Barrier / release agent" between those two.

Surprisingly it can happen with ultrasonic cleaned cases as well. When they are "to clean".

Just thought I'd share... since it took decades to finally get an answer...
 
Thanks everyone, After a lot of web research I found I can get 6.5/284 brass and also a 284 case neck expander 7mm is the same. I've been looking for ammo and brass on the internet for 2 years probably more, put my name on lists for seasonal runs, I don't know when those seasonal runs occur but not very often cuz they haven't come up yet. It is a fun gun to shoot and was running out of resources I'm glad I found a way to keep shooting it. On a side note, the scope on the the gun is 30 plus years good at 100 yards is not so great at 200 any suggestions for reasonably priced scope where the target is still visible at 300 yards?
 
I have a 6.5mm284 barrel. I found the dies cheap, seems the previous owner was misinformed and misguided, he ground the bottom of the die because he had a short chambered rifle. No problem for me, I adjust the die to size the length of the case when off setting the length of the chamber. I have a good grip on the concept of zero, for me there is the 'either side of zero'.

I start after I have the dies, cases and barrel, just over a month ago I started rounding up cases, my cases. I needed 300 belted magnum to start with so I started sorting. I now have the cases in order.

Belted magnum: In the beginning little concern was given to the chamber in front of the belt, it was a matter of pinning the case to the rear and pulling the trigger. All the case body had to do was fill the chamber. Seems nothing has changed. I have a box of Hornady 7mm Remington 2/Magnum with coated bullets. The length of the case from shoulder/datum to the case head is shortern by .020" than any of the 200+ 7mm Remington cases I have.

When I install the barrel I will decide if the rifle will shoot new factory ammo with lots of room for the case to travel or cases that have been sized to minimum length/full length sized.

Mr Guffey, what you said reminded me of a question I had on belted magnum cases. After these cases are all once-fired, will you size them to headspace on the belt or on the shoulders? I would go for the latter.

Not trying to hijack the thread, but just remembered the question.
