Too Much Resistance While Full Sizing

[jpjulian]

Thoroughly clean your sizing die and start over. Is it possible that you used a different lube on prior cases? Different lubes don't play nice with each other. Been there.

That's a real possibility that I've only read about and have never experienced. Maybe!

Years ago, RCBS said in their news letter - Wax case lubes are the main cause of people returning there fl dies, to remove stuck brass.

Avoid the waxie build up.

Die could be really rough. Just had to polish my new 20BR Redding die because of this.

About every 500 rounds or so I use a good carb cleaner and then dry them really well, takes care of any wax build up.

I do not believe your issue is due to the lube. "Imperial Case Lube" assuming you mean Imperial Sizing Wax, in my experience, is one of the best if not the best lubes on the market IF applied correctly. I have literally sized thousands of cases with it and never had a stuck case or difficulty sizing a case. You don't need to go into the weeds on the lube issue.

You said sizing was fine with Redding Die. Unless I am missing something, which is possible in my advanced age, the problem seems straight forward: "it's the die"! Use the Redding Die! Problem solved.

I had the same thing happen as the OP with imperial. I changed lubes and the issue went away. It rarely happened but did happen twice as i recall. It was as iff the case was dry but had plenty of lube.

Take a case and put some dyechem or sharpie marker all over a case and slowly run it up into the die. Stop when it gets harder than "normal".
That will tell you quickly where the friction is.

I contacted SAC, and I took some measurements of fired brass. I learned that my chamber is too large. I will get this fixed.

I should also mention that SAC's response was timely and very helpful. Good customer service.

Previously used a Redding full size die with no similar problem.

 

[lgwatson]

I will use the Redding.

How do you fix your chamber?

How do you fix your chamber?

Have to have it set back and rechambered.

Have to have it set back and rechambered.

If you have a Redding FL die that works as it should with your "out of SAC spec" chamber then just use the Redding and hold off on the set b ack until you need to set it back. If the barrel is displaying the accuracy you are happy with there isn't any need to "fix" it.

That's the plan. How are you doing Jerry? I hope you're doing well.

I am still on top of the ground instead of beneath.
I am blessed. My next oncology follow up is Tuesday and results on Wednesday.
Hope you and yours are well.

Thanks, that makes sense.
