300 WM Resizing Die Issue

[Main Frame]

So I am using a Whidden resizing die with a .337 bushing. I have to put a ton of force on the die to de-prime the brass and then put all my weight on the level to lower the piece of brass out of the die. I don't think it should be this hard? I have Whidden dies in other calibers and they aren't near as hard to cycle the ram.

What could I be doing wrong?

Are you lubing the cases? Something you're doing isn't right.

Yes. I spray some Hornady One Short on a paper towel and rub the neck and shoulder on the paper towel. I’ve never had the issue and can’t figure it out. Trying to load some rounds to take to Mexico and I’m running out of time..

Try lubing inside the neck

If you're using an expander ball in your sizer, it's POSSIBLE, it may be getting stuck in the neck. I put the tiniest bit of imperial sizing on the ball the first time I use it. I prefer imperial to one shot for case lube and I've read of guys solving some issues like this by going to imperial. Get some lube down the whole body of the case - you're not just sizing the neck and bumping the shoulder. If this isn't it, I'd suspect the die is out of spec.

If it's an FL die you need to just spray the case. There will be enough get inside the sir to help. The body is the most friction. Not the neck. Use dry lube inside the neck. I use a universal decapping die to deprime. Then size. I would also check to make sure that bushing actual is what it says it is. Clean the die. Make sure everything is adjusted correctly. I suspect the issue is lack of lube on the case body.

Sizing bushing too small and the neck expander is opening neck up. Your case walls are too thick for that bushing. You may need to turn the necks down to use that bushing. What neck tension are you after?

To answer your question, I am not really sure what neck tension I am trying to achieve. I ordered the bushings based on Whidden's recommendations. They recommended the .336 so I ordered: .335 .336 and .337. None of them are allowing me to cycle the brass through the die. I do not think it is the bushing because I can remove the bushing from the die and it still will not cycle.

Take out the expander rod. Will the case go then? Bushing dies let you set different neck tensions per the thickness of the case neck walls. You really need to turn the necks to uniform them for best results.

If the neck expander ball is not the culprit then take a black marker and paint the whole case. Run it back in the die and see if there is marks on the case.

This is the place to start but you really need to take some measurements and figure out what bushing you need.

Have you ran a new peice of brass through it or just once fired? Maybe the chamber on you rifle is out of whack a little and the cases are expanding beyond spec after firing?
I’d try with new brass and see if you have same issue, if so, sharpie the case all over and see where the rubbing is occurring.

Thanks for the input. I plan to run a new unfired case through it when I get home. Then try to paint a case and see if I can find any rub marks. I will report back.

The dies he has are full length with neck bushings. He said he took out the bushing and it still won’t go. The neck expander maybe wrong size ? Or the die is wrong or his rifle has a big chamber. He also stated he has several other Whidden dies so I would think he knows how to load. I am not a big fan of the spray lubes and prefer the imperial sizing wax. Sometimes that spray lube ain’t got enough slippery in it for Big rifle cases.


I stuck a 45-90 case one time using spray lube. Now I only use spray lube on my pistol brass.

I painted the case and it is rubbing all around the case about 1"-1 1/2" above the belt. I don't know how to post pics but can text it to someone to post.
