Need HELP

[Stumps13]

in the process of depriming and f/l resizing I have encountered the following.
the thickness of the case rim on 257 Roberts -Winchester Super X will not allow it to enter and slid into the correct shell holder. All others no problem but I do have 20 rounds That just do not allow it to happen .
Any thoughts would be helpful.

Thanks

You might try a different shell holder.

thought of using a different shell holder but of course I do not have a RCBS #4

Presumably you are using RCBS #3. Shell holder sizes are not in size order for any manufacturer that I know of. Lee shellholders typically have a bit more play which could help (I think you need Lee #2). If it's one piece of brass, I'd set it aside and move on. I find the most common reason for this with the correct size shellholder is a nicked or bent rim; nicks can be lightly filed down, bent rims generally are in the scrap bucket.

RCBS says a 3 or 11. If you buy their dies they recommend the 11. A call to their customer service will get you your answer.

I would check this brass with the bolt on the rifle to be fired in. If it does not slide into the bolt easily then it would be useless to go to the trouble to process these cases. If it does fit into the bolt then proceed with the other suggestions.

There is a difference in the extractor groove between brands of brass. In the Lyman 45th edition they recommend the #8 shell holder, or the #2 if the the #8 doesn't work. Oddly Lyman is the only company to note this. RCBS lists their #11, Redding and Bonanza their #1, and C-H their #4. Don't have a reference for Hornady.

Many thanks to all the responses to my question.
The problem has been solved. Using RCBS shell holder #11 I have been able to full length resize and deprime.
The resized and trimmed brass now works like it originally was intended to do.
many thanks for all that did to solve this problem.
