Primers

I made a mistake I'm new to reloading and I bought new case and installed primers before sizing. Can I put them in like a oil of some sort and let soak for like 48 hrs them press them out so I can size my cases and not get blowed up? First learning curve.

You can leave the primers in, remove the primer pin from the expander rod, resize without pushing them out. Or if it's only a few it's often advised to slowly deprime them with your sizing die. Operate the press handle slowly and wear safety glasses just in case. It's been proven many times that it's almost impossible to 100% deactivate all live primers with oils. New factory cases often are not sized at all since they are supposed to be correctly sized by the manufacturer?

As Rg1 said, most cases are already sized and you should be able to use as is. You can try an empty new case in your gun to see if the bolt closes ok. If yes, good to go. If not and there's more than just a tad of pressure required, then probably aught to bump the shoulder back in a full length resize.
 
What's the caliber? I'd test them now in a Lyman gauge or barrel and probably use as-is

As mentioned-just remove the depriming pin from your sizer and don't use an oil based case lube. Getting all the lube off is more difficult. Tumbling primed cases may leave media crumbs in the flashhole so each case needs to be checked with a light to make sure this is clear before continuing.
While it's not recommended,I've never had a primer POP when pushing live primers out of cases.
 
Somebody already mentioned it, but these cases of yours are new and don't have to be resized prior to first use. Go ahead and load em and shoot em.
 
I would not want to put oil in the cases. If a small trace of oil remains it could jeopardize the powder charge...

Pull the depriming pin as explained. Also I would FL size the cases and check their length and trim if needed. Simply because that is my inspection process.

When reloading I assume very little. I also include uniforming primer pockets of new brass.

It takes only one flaw that got through the manufacturing process to ruin your day. I have found plenty of rejects of new brass.

It's your process and your butt. The reason I do it is because I think I would look silly with one eye or missing a finger...

As a newb, too, I also had some cases already primed and when I set the bullet in the case, it fell into the empty case! :eek:

So I did as said (above) - removed the depriming rod and switched dies, re-sized, switched dies (SS press) and carried on. I still haven't figured how I was able to initially decap the case and so it shoulda been sized at that time.

Why it was seemingly unsized - and without a fired primer - but it was big enough to let the bullet drop in. I've been running ALL my cases through the de-capping/resizing die (again?) before beginning a reload session.

Welcome to the newb club!
 
The last new cases I bought had to be resized, bullets weren't tight enough when seated. These were new Win. .223.
 
Lots of good answers but without knowing what the caliber is they may not all be right. While some new brass may be ready to go its not a certainty. Especially bottle neck rifle, the necks are often dinged and dented and the shoulder may not fit your chamber quite right. Its been a long time since I bought any new brass but I'm guessing 9mm or 45 ACP or 38 special are good to go right out of the box. What ever the caliber is you should check a few and see how they fit in your gun. More than likely you can just resize the necks to make sure your bullets will load properly. If your main concern is whether or not the primers will go off, they will not as long as you remove the decapping pin, but as always, have safety measures in place, such as glasses.
 
Put the unsize, primed cases away. Reload the others correctly. When you have gained bit of experience/knowledge you'll know how to handle the "situation".;)

Primers aren't as delicate as many think, oil for 24 hrs may kill a primer, but I wouldn't bet on it. You could just run the cases through the sizing/decapping die and save the primers (don't slam the case up into the die, just go slowly). Or you could remove the decapping pin and size then reprime (most dies have the expander plug on the decapping stem so the case necks would prolly be undersized if the stem were removed).

At least you found the "problem" before you completed reloading those.
Go slow, Double check everything, and most important, have fun...
 
In addition to removing the decapping pin from your die, I'd suggest lubing the case (Imperial sizing wax - Mink Oil works fine also) if not using a carbide die. Many brass makers tumble the brass to clean the cases. In the process case mouths sometime get dings or are out of round. Neck size the brass and then chamfer and debur the mouth. The last 2 steps are also needed each time you trim the case.
 
FWIW, I always run new brass through the sizer just to uniform them before trimming for an X die if they're a bottle neck round. Straight walled brass still gets the same treatment as once fired brass - just without the cleaning step.

There is no guarantee soaking the primers in oil works, do not do as I do but I removed primers from cases that were suspect meaning 5 rounds out of a 20 box of R-P 30/06 did not fire, and then the 5 rounds were passed arount to ever shooter that has a 30/06 rifle and noting. There were at least 5 attempts at busting the primers.

That afternoon the 15 fired cases and the 5 that failed to fire showed up here. Straight away I instructed them to call Remington, I told them the phone number was on the box, they threw the box away, anyhow I checked that ammo everyway I could think of and then I removed the primers and then reinstalled them back into the same cases they were removed from. After installing the primers I chambered all 5 cases (one at a time) into one of my M1917 rifles with killer firing pins and busted all 5 primers one after the other.

I should have taken one of my rifles with killer firing pins to the range when they called but I honestly thought if they thought there was something wrong with Remington ammo they would call Remington.

The rifle was a new Ruger, I measured the fired cases and could not find .001" difference in case measurements between the fired and failed to fire.

I know, there are a few reloaders that are shocked my rifle with the killer firing pins did not shortened the case between the shoulder to the case head. And you all know what Truthful James said about that.

Check if they fit. If so.......

Load em up and shoot em unless you are bench rest F class and it does not sound like you are there yet. (grin)

I contend all new brass needs to be once fire before its ready to serve as the base for a 1/2 MOA cartridge capability anyway.

What caliber, what mfg brass and what shooting class are you in or after?

Even Lapua needs to be "conditioned"
