.223 shell holder set for headspace shoulder bump

[pei precision]

hey guys looking for some help i recently got a new rifle and wasnt told that the chamber as cut pretty tight its a .223 chamber throated for a 80 gr berger(which im shooting) now my issue is that i full length sized the brass(winchester) and the loaded round got stuck bolt would not close.\

im having the cartridge removed after i failed to be able to extract the round and after talking to the previous owner was told that the shoulder needs to e bumped 2 thousands and i was not aware of this so im looking for a shell holder set so i can find the holder that will bump the shoulder back when sizing everything i can find lists competition shell holders from #11-#2 from lee and redding

from more reading the #10 should be the .223 case size holder set from redding

my understanding is that you find the shell holder that is your "zero" shell holder and then the number under that holder will be 2 thousands bump so my question is who in canada carries the set i need (lee press/dies) and also will the sets that say they are "universal" hold my .223 cartridge base thanks in advance this is my first venture outside of a factory rifle. feel free to pm me if you have a set and can give me some feed back or if you have had this issue.

Chambers and dies vary in size and sometimes you to make special adjustments.

If your die is not pushing the shoulder back far enough then buy another and lap the top of the shell holder.

I had a .270 with a tight chamber and had to lap .003 off the top of the shell holder for the full length sized cases to fit the chamber.

On the flip side of this I have a standard .223 Lee full length die that will push the shoulder back .009 shorter than a GO headspace gauge. Meaning over resizing the case if the die touches the shell holder.

Your die is not pushing the case shoulder below the red dotted line below. The blue dotted line shows you when the case is squeezed in the die it becomes "longer". And its the last few thousandths the case is pushed into the die that it becomes shorter than its fired length.

If you buy a Hornady cartridge case headspace gauge it will tell you a great deal about the cases fired length and resized length.

Below a fired case from my AR15 rifle "before" full length resizing, after full length resizing the shoulder is bumped back .003.

Also the Redding competition shell holders will "NOT" push the case into the die as far as a standard shell holder.

Meaning the Redding shell holders are for dies that push the shoulder back too far when they touch the shell holder.

Your problem is you are not pushing the shoulder back far enough.

Try screwing the die in further and making sure the press is camming over. If that doesn't fix the problem you then lap the top of the shell holder which allows the case to be pushed further into the die.

If this is happening with the die all the way down to the shell holder, as mentioned above the shoulder is not being pushed back far enough. So the top of the shell holder can be ground or polished down a bit OR take 0.010 off the bottom of the die, making sure you round any sharp edges at mouth of die.

Are you overcamming the press ?

is it the shoulder or the base of the case that is Jaming

does factory brass Jam ?
Do You need a small base sizer die ?

Do you have 1 pc of Brass that does not Jam ?
