A friend of mine repaid a favor that I did for him by giving me a couple hundred once fired 300 WSM cases. I tumbled the cases and ran them through my Lee Collet Neck Sizing Die, removing the primers. Because I have previously made this mistake, I always take a bullet by hand and make sure that I cannot fit a bullet into the case neck. 10 out of 10 slid all the way in. I ran the 10 back through the Lee Collet Neck Sizing Die. Same problem. I tried running them through the full length sizing die, and they got stuck about 3/4 of the way into the die. I applied a liberal amount of One Shot on the case and into the die and the cases continued to get stuck. I adjusted the die several ways and even removed the center pin from the die, to no avail. Is it Lee dies? Should I try another brand?

Any help is appreciated.

Without knowing exactly the way the dies are adjusted or made, I can say the one and only time I tried "One Shot" was the last. Yep, it was shaken, applied well, and the cases still nearly got stuck, and would have if I didn't sense something was wrong, and backed off. Went back to regular RCBS and Dillon spray lube, and all was back to normal.

In my experience, "One Shot"= Garbage.

To set a collet die, in my press, I screw the die down until it won't go full stroke, when sizing a case. then I screw it back out just enough so it does go full stroke.

Some presses are a little different to others, (that's what it tells me in the 'destruction manual')

BTW have you checked if the neck sized cases will chamber in your rifle.

I think the .300 Whizz'm has much thicker neck wall thickness then other more pedestrian .30 calibers.

Could be you need a smaller mandrel for it then other .30 calibers?

GardDog223,

While you may have other problems, throw the One Shot away and get some Imperial Sizing Die Wax (sold by Redding). I have no doubt that more cases get stuck using One Shot, than all the other lubes combined.

Thanks Don, the Imperial Sizing Wax did the job. I will use the One Shot cans for squeaky doors and stick with the wax from now on.

I was taught some 30 years ago that you neck size brass after it was fired in your chamber and not one from some other weapon.

Has that changed for was my mentor full of it?

In general that is right, but sometimes the chamber in the second rifle that the brass was not fired in has a chamber very close to or smaller than the one the brass was fired in, thus giving no problem.

All in all though, good advise.

[GardDog223]

Maybe my nomenclature is off.... The neck sizing collet die was used because the neck of the brass case was too large and a new bullet could fit through the neck of the brass case without stopping. This has happened before when reloading .308 rounds from my own rifle, not just with the brass given to me.

If the consensus is that neck sizing previously fired brass should only be done with brass that was run through my gun, is previously fired brass that is for sale on auction sites not in the need of neck sizing?

is previously fired brass that is for sale on auction sites not in the need of neck sizing?Yes, any fired brass that didn't come out of your gun will probably need Full-Length sizing, not just neck-sizing.

If they will chamber and the bolt close normally, then you could neck-size only.

Okay.... that must be where my mixup with the replies was. I do full length size and only neck size when the bullet can pass through the case neck, regardless of the original owner of the brass.
