Anyone have issues neck sizing 8X56mmR brass in the Lee die set with once fired PPU brass?
just neck sizing using the RCBS lube (and a decent amount of it) it was a bit of a bull to get to size.
could it be my M65 chamber? funky dies? even more lube?
 
I shoot a steyr m95 carbine, I reload privi brass with rcbs lube and the lee 2 die set, it never gave me any problems.

Question, you say you are neck sizing only. Is the body of the case touching or rubbing inside the body of the die? Meaning a fat chamber and a skinny die.

Normally only the neck of the case would would contact the die. Meaning you should be able to size the neck with one finger.

And many people do not lube a case they are neck sizing only. And the neck and shoulder of the case is annealed making it softer.

When I full length resize once fired 7.62x51 NATO Lake City cases it can take a great deal of force. This is because the ammunition was fired in a larger diameter machine gun chamber.

Many older milsurps used in the field would have rusty chambers and the chambers were cleaned up with a sanding stick. And this will make the chamber larger in diameter.

Even if the rifle wasn't refurbished or anything like that, military rifles tend to have more generous chambers because feeding/extracting flawlessly in dirty field conditions is critical to the usefulness of a rifle in battle. The Lee Enfields generous chamber is a classic example of this, but its a common practice to a lesser degree for most rifles put into service.

Checked the brass and I think it did not show any signs of the rest of the body touching the dies, but I could be wrong.
I've also noticed that seating bullets takes more pressure than normal almost like it needs a flaring die with the flat based hornady bullets,
unlike my 303 using flat based bullets.

I guess you do not know I collected milsurp rifles, and never read my postings about long fat chambers. And how much fatter the chambers got from sanding the chambers because the rifles got a little wet when it rained. Did you know they even fight fight wars when it rains. :bangHead: How soon they forget.

I didn't know you collected mil surps, but what I said wasn't directed at you, per say, either way. I was simply adding more info to the thread, trying to build upon what you had laid down.
 
It will stretch to fit the chamber more every time it is fired unless the die is enlarged to the same specs.Or if one just neck sizes the fired brass.
 
with a bad oversize chamber in an enfield sometimes the cases will suffer from head separation the first shot. and if they don't and you full length resize they will on the second. btw 2 drops of oil on a case ? do you use a lub pad or? try more oil to much and you will have case dints around the neck
 
How bad would a "enlarged" chamber be for brass life?

You need to find out "why" the case is so hard to size in a neck sizing die.

Measure a new unfired case at three points along the case body, and remeasure after firing. How much is the case expanding when fired.

Color the fired case with a black felt tip marker and rechamber and check the rub marks.

The problem when the case body expands excessively is it can warp and cause the bullet to be misaligned with the axis of the bore when reloaded.

Bottom line, you need to find out why your cases are expanding in diameter so much they are hard to size in a neck sizing die.
Meaning do you have a over sized chamber or a bad undersized die. The body of a neck sizing die is not polished like a full length die, and not designed to size the body of the case. And the die diameter is larger in diameter than max chamber dimensions. And the case body should not contact the inside of the die neck sizing die.

NOTE, I just did a Google search and the only dies I could find were a Lee 2 die set and their die is a full length resizing die. Are you sure your die is a neck sizing die?
