Reloading unfired brass
 

I have 2 boxs of 35 Remington ammo that will not chamber all the way in my 336... I was thinking about pulling bullets and powder and running them through resizing die and then reloading them... can that be done???

Yeah remove powder and the decapping pin out of die.

Was it new when you got it ? If so I always full length resize the first time then fire size for that gun.

Oh I think you are saying it was loaded ammo ? If so factory ?

Yes loaded

If it's loaded factory ammo I'd definitely take it back where you got it. If handloaded you can pull the bullet and dump the powder. You may want to weigh a charge after pulling the bullet so you can recharge the cases with the same amount. Lube the cases and resize. I'd recommend Hornady One Shot to lube as it won't contaminate the primer or powder. But BEFORE YOU SIZE back off the decapping pin but don't remove completely. You need the expander ball to size the inside of the case mouth on its way out of the die. Just back the decapper out enough so it doesn't contact the bottom of the case (primer).

Bronco has it - don't remove the decapping pin, just withdraw it far enough such it only penetrates through the case neck.

I might do a little measuring to understand why they don't chamber before I did any resizing though. Something is amiss.

Forgive me if I'm easily confused - is this FACTORY ammo?

Yes factory Winchester 35 Remington ammo bought at midway USA on clearance... Never again Winchester!!!

Weird... Can you tell where it is making contact? Is the headspace too long, or the bullet (assuming headspace)? Is the shoulder bulged at all?

Yeah I said remove the decapper my bad ! Are there anyou dents in case after trying to close Bolt? I would pull a bullet on one then try to close Bolt if it still not close try to resize one.

Well as long as its factory ammo, give winchester a call and have the lot number handy. They should replace it for you or at least refund your money. Big green did it for me for a lot of 17 HMR ammo that had contaminated propellant and the bullets were getting lodged in the barrel. They sent me a check to cover the replacement cost.

It's strange that factory ammo isn't chambering correctly. I'd do what muzzlestuffer suggested.

I bought a digital grain scale and I'm gonna take 3 bad rounds pull bullets and weigh each charge then I'm gonna full length resize them add charge back to case then re seat bullet back to factory length... then test fit to see if it chambers

One more thing to try is take a black magic marker and make the entire case and bullet black then run into chamber until resistance is felt pull out round look for wear marks

if the brass is new and unfired you might want to check the length to see of the neck is too long. might need trimmed to the right length before loading and crimping.

Seriously I would give Winchester a call and see it there was a problem with that lot of ammo.
But out of curiosity and it may sound dumb, but did you try any other ammo? I can tell by your posts that you do reload. But the last time you fired your rifle did you pick up the spent brass? Maybe you shot at an animal and forgot or lost the spent casing. I could be that the case ruptured and there is a small piece lodged in the chamber. Seems very remote. But stranger things have happened.
