Cases denting on shoulder

[kylelowry1]

im new to reloading and i am reloading for a .300 ultra, when i run the sizing die through the case, they come out with dents on the shoulder of the case, what could be causing this? I loaded 20 shells no problem, then this started to happen.

too much lube on the shoulder, it could be starting to build up in the die and that is why it didn't do it right away.

You made be using too much lube and it`s building up abit in your die. Hydrolic pressure causes the dents. Try less lube for the next few rounds and see if it goes away.

Use a very light coating of lube. I have switched to Lee case lube, water based and when dry does not dent cases.

If you have some aerosol brake parts cleaner, flush out the die to remove the buildup of lube. I've had the same thing happen myself.

thanks alot, that was the problem, working great now.

Probably too much lube on sholders but it could be the air holes are plugged. Look at the top half of the die and you should see some air vents. Give them a poke with a pin.

When you shoot the ammo, you might be surprised at how well 55,000 psi smooths out those cases...

Dents are no problem. As suggested, use less lube on shoulder areas.

so the dents are no problem?it is okay to load these cases?

Load them up. Just ignore the dents and load as you would without the dents.
