308 Brass not fitting into shell holder

I didn’t read all the drivel in this thread, so forgive me if this has been brought up already. But I have found Norma brass in particular has a tendency to just barely fit in my (RCBS) shell holders and case trimmer. I don’t know why, but others seem to have reported this as well.
 
Just of late I am having trouble inserting some of my fired 308 brass into the lee shell holder on my press. I can force the shell in then I have to force the shell out again. I am using very tame loads I would think, I have run the verniers over the offending brass and found maybe a 1 thou difference in the shell base thickness. Any one else having the same trouble?? The other brass, all PPU, fall into and out of the holder but I am noticing a couple every now and again.

I’ve had this issue when the brass had ejector swipes fro over pressure previous loads.

Before sorting and gleaning through the drivel read the book of vanity first, in that book it is said it is better to receive the wrath of a wise man the rhetoric of fools.

I have suggested a reloader learn to measure before and again after. I would suggest you check the fit between the shell holder and case head first and again after firing. It is not a know fact that shell holders from different manufacturers do not fit the same. My RCBS shell holders fit like a hand me down shirt, the case fits anywhere it touches meaning it is a loose fit. The loose fit makes the RCBS shell holder my favorite because I can form/sizes cases for long chambers and short chambers.

I have other shell holders not made by RCBS that are almost perfect fits to the case, I have always liked that because if for some reason the shell holder fits before firing and does not fit after firing I know the last load was too heavy meaning the load crushed the case head. And then there is that part about determining if the case stretched between the case head and case body.

To be clear, the trouble I've had with Norma brass is that it appears that the groove is slightly shallower than other brands, and occasionally interferes with a variety of shell holders. It's as if Norma forms it with a different tolerance spec than everyone else. How this could be is a mystery to me. I haven't really looked into it. I just stopped buying Norma brass.

Again, a builder of bench rester type rifles had a problem, he made and sold rifles with a wildcat type chamber and there were not a lot of cases available. He started out trying to form cases according to the experts and the Internet, noting worked so he called me. The first thing I had to decide was; 'could it be done?' After a few attempts I could form the cases without fail. (one more time) Between us we have 6 lathes, cutting the extractor groove deeper but that did not change the diameter of the case head and the case body ahead of the belt so I had no interest in salvaging his cases that had been fired with excessive pressure.

The extractor groove diameter can be measured, the expansion ahead of the belt can be measured and then there is the case head diameter and the cause of the expansion in front of the belt, I have read reloaders talking about the expansion in lofty terms and I have always felt they were causing the problem.

Yea I got a lathe too but mine you can't carry under 1 arm. Heck you can't even carry the chuck under 1 arm. We split my 24 inch tractor wheels in it when we took the gap out of the bed. Its a Summit. But I still say that if you need a hammer or a lathe to get cases in the shell holder, you are danger to yourself and others that shoot near you.
 
Hi again good folks, just to throw a spanner in the works I found for once in my life I have made a mistake. :(
I in fact have a lee press BUT I was using RCBS dies and Shell holders all the time, bugger. ;)
So going back to my original question that in no way referred to hammers, has any one had the same trouble with RCBS shell holders :):):)
I am a boilermaker/welder by trade and I am well acquainted with the old axiom of , "when in doubt use a hammer, the bigger the doubt, the bigger the hammer."
I will now sit back and let battle commence. :-)
 
Russ I had the same problem with 338 Lapua when I fist started loading for that caliber. The Lapua brass would not fit in the RCBS shell holder. A call to RCBS and a new shell holder was on the way. The original 338 Lapuas were made from 416 Rigby or 404 Jeffery brass and when Lapua made the 338 version the shell holder from the parent brass did not fit the new brass. So a new shell holder was made that did fit. Have you talked to Lee or RCBS, they are willing to help when these problems come up.

EBB, I said we had 6 lathes between us and said I had one that I could carry under my arm, that is the one with two chucks. And then I thought about it; it is not like 'now there are 7' but I did forget one that I am going to sell. I have two of those but one is complete and the other I purchased 'JIC" as in just in case something goes wrong with the other.

A "proud" primer after firing

Lee may be one of the shell makers that does not have a groove cut down below the level of the case head on the shell holder. Most do have that groove to allow a primer sticking out a little ("proud").

If you do not have that groove going out to the primer hole in the shell holder, grind one. +tK3keCfTra+qikLinFZjg by Larry Malinoski, on Flickr

Right one has a factory groove. Middle one does not (Lee?), left one is one I ground a groove to clear a proud primer.


No.

Sorry to opine here among the experts but that is not correct. The grooved holder on the right is the Lee Holder. The middle one looks like . .. uh....it needs to be cleaned.

Here are three Lee holders from their little Lee plastic boxes. The older ones came in round plastic cylinders.
