Well thanks Uncle Duke. I appreciate your candor. Thanks for the translate, will do! Happy New year
You too sir!

I'll take a stab at your question.....
I THINK what he's trying to say is that most of us in the reloading forum aren't metallurgists. If I understand your post correctly, and I read it several times, you suspect brass fatigue as the OP's problem. That is, the cases don't have sufficient elasticity to release from the chamber wall after peak pressure subsides upon firing. Hence, they are difficult to extract.
Short of a more probable die setting issue IMO given what I surmise to be a newer reloader, you may indeed be absolutely correct. But respectfully sir, can you "dumb your thoughts down" a bit?
Your target audience? They run the gamut from experienced reloaders to those who may have an interest in the hobby, but have zero experience with it. You're speaking Greek to many who may not be operating presses in Athens.
Did I read that wrong Uncle Duke? If I did I apologize for the long windedness. I was under the presumption that the extraction issue was post firing not pre firing. If it is after the shooting event the rifle chamber becomes the new de facto resizer from the the higher pressures placed on the internal surfaces of the case walls fire forming against the chamber's geometry. This event cancels out any input made from a reloader having an effect on the case after that moment only.
Sorry to be obtuse. Thanks for looking out for me.
You're an insulting and sad person.
Is that brief enough?
Sincerely,
your Son.
My Son,
Nice effort, However, Your obsessive need for validation requires me to answer succinctly, No you not have mastered brevity.
Sadly yours Dad.
P.S. I am so sorry that you got in trouble and got sent to Boys Village Finishing School.

I have heard that there is now medical help avaiable for those with "pressure problems" and difficulty "working up a load". I'm just saying.......
No apologies necessary! And no, you didn't read that wrong. I did! MY apology! OP states POST firing. And agreed....chamber geometry indeed now the determinant...
Sounds indeed like a classic pressure issue. Curious as to the OP's powder charge weight, and both the cartridge overall length and the case length. Op mentions a range, but not the specific charge he is using of IMR4320.
The "Game King" 130 grain bullet that the OP mentions as being used would be Sierra's #1820, which Sierra Edition 5 7th printing indicates should have a COAL spec of 3.300".
Case trim to length is shown as 2.53, with a pre-trim spec not to exceed 2.54.
Charge weight per Sierra Edition 5 are 43.6 on the low end, and 49.4 on the max.
I think the OP's answer may well be found by putting a caliper to those rounds.

You dont NEED that shit. A regular FL sizing die will work fine. The point of my post was to eliminate possibles, not recommend a bunch of shit the OP dosnt need.
RCBS recommends cam over with their FL dies, as per instructions. The OP already stated he has a set of RCBS FL dies.
That being said Ive camed over many brass in various guns, and the brass still lasts along time.
ALL FL dies recommend camming over in the instructions.
That sizes the case to the minimum dimensions. WHICH IS NOT REQUIRED.
If you want to over work your brass, and reduce the life through the brass moving forward with every firing, then go for it. Overdoing the sizing leads to case head separations, neck thickening, needing to trim more often, and even neck splits.
Some people blindly follow the directions, which are written the be safe, but not confuse people. Other people like to learn how to do things better.
