Shoulder Bumping & Neck Sizing

Disagree-not that you didn't learn anything BUT:
The OP stated he is a NEW reloader. There is not a single post by guffey that has helped this NEW member. If I am reading it correctly I don't think he (the OP) has returned. guffey is a true pro at not answering ANY asked question.
I am becoming more convinced it is intentional, and derails a post by impossible responses to decipher. Then sidetracks some very knowledgeable folks who try to stop the pain by responding to his whacked out wording.

Yeah he is a destructive presence on all of the sites that I have observed including Reloader's Nest and The Firing Line.

Maybe I'll start a thead on the feeler gage as a companion to the press.
At least we're talking on this site. Been pretty low on traffic since the big
Change to the new site.
Best,
 
The feeler gage be be used two different ways; one way is to place the feeler gage between the deck of the shell holder and case head. I find the biggest advantage to the feeler gage comes when I need to form/size cases for short chambers. I can shorten the length of a case from the shoulder of the case to the case head .012" when I use a RCBS shell holder. The feeler gage also allows the reloader to increase the presses ability to overcome the cases ability to resist sizing; and then there is one of those 'and the then' moments. A reloader can use the feeler gage to when they think/believe they need a small base die.

A feeler gage can be used to increase the length of the case from the shoulder to the case head; I use a .014" feeler gage to adjust a 30/06 die off the shell holder when sizing cases for a rifle that has a long chamber. The chamber is .002" longer than a field reject length chamber. A famous gun smith was given credit for all of the long chambers, it did not bother him because he was not sensitive.

Redding competition shell holders are nice, I do not find them necessary nor do I find it necessary to grind my shell holders and or dies.

The feeler gage does nothing to the press. All it does is change the position of the case relative to the die or change the position of the die relative to the press.
Your choice of words seem to be deliberate obfuscation. Can you adjust the obfuscation impulse reflex with a feeler gage?

In other words you can bump the shoulder .012.

The feeler gage also allows the reloader to increase the presses ability to overcome the cases ability to resist sizing;
So can grinding a shell holder, much easier.

It's obvious you never had a custom chamber with a tight based. Matt
 
Catfish. is that you, do you know why I call you catfish?

Did you get my message? You will not believe it but I found an eye doctor that help dysfunctional on the Internet with $hitty attitudes. Would you like to know how he does it?

But "bump" has a connotation of violence. We need to standardize on "gently move" the shoulder. Our goal should be to become more brass friendly.

Even easier for .223 case family users is to not use the shell holder at all.....fits right in the ram slot......NOW boy you can bump .....er...gently move the shoulder back a full 0.315 for those mini-wildcats that are so popular.....just do it gently .....with feeling....and this method really allows the case to float to minimize those concentricity problems

Yeah Matt, I get the impression from his posts that Guff likes 'em big in the back-end.

Base of the case head yes depending on the shell holder .005 it's about the most you can use. Larry

If you are going to reinvent the feeler gage you may as well get it right. You could do a search but in the beginning there was some ugly criticism at the suggestion. I do not expect you to quote me but the .005" is a little shy of the actual. The RCBS shell holder is my favorite, on most of my RCBS shell holders I can reduce the length of the case from the shoulder to the case head by .012" and then there is that old saying about fitting like a hand-me-down shirt; the RCBS fits the case only where it touches.

I use the feeler gage to size cases for short chambers. There are shell holders that fit, there is a use for shell holders that fit, it is not my job to convince any one it works.

It is about this time someone will suggest grinding the top of the shell holder or bottom of the die. As luck would have it I am one of the few that has a tool that does just that.

I put guffey on my ignore list a long time ago. If most of us did, and did not respond to his distractions, he might get the hint and stop or go away.

When placing the feeler gage between the top of the shell holder and bottom of the die the reloader can adjust the die from +.001" longer than go-gage length to infinity. Redding Competition shell holders are nice, I have one set, I do not use it but I have it just in case. I have a rifle with a long chamber, the Redding +.10" does not have enough deck height.

Again, I have a M1917 30/06 with a chamber that is .016" longer than a minimum length/full length sized case. When sizing/forming cases for that chamber I adjust the die off the shell holder with a .014" feeler gage. After sizing 280 Remington cases with the .014" gap my cases when chambered have .002" clearance. And one day someone will do a search on the .003" clearance and the .002" clearance and still wonder where it came from.

If I chambered a minimum length/full length sized case in the M1917 and then pulled the trigger reloaders believe I would experience case head separation or as they say case stretch between the case head and case body. I could ask them why they believe the case would experience stretch between the case head and case body but the question would just make them mad.

go-gage length to infinity.

It is possible to modify a go gage to go from go-gage length to infinity. I see no advantage to going to infinity but I have found chambers that were .020" longer than a go-gage length chamber, I did that after I was told it could not be done.
