FL Sizing Problem

wow, WOW! Good to see YOU back Ken

How's the PNW treating you?

hey Al!

Glad to see YOU still kickin' too!

PNW's just fine with us - surely a big improvement from that other place, CA.

Dunno what my old ID was in here, or whether Wilbur jumped on an opportunity to delete me from all records, a thing I might not blame him for doing, but I drop by to read now and then.

Not long after coming up here my feet swole up and turned black. They tell me it's these little checkvalves in the lower extremity blood/hydrualics that leak because of diabetic degradation. so now they hurt all the time. I don't blame Washington for it but it was a strange coincidence.

Anyway, I'm not in a chair (yet) and they tell me that there shouldn't be any need to amputate but now and then they get infected so they wrap one leg or the other up for weeks. Can't find shoes or boots that fit for long and some days there's no way anything is going on them at all.

So this leg/feet thing makes it more difficult to get out to the range and nasty to get downrange and back for the targets. I content myself mostly with shooting pistols in my backyard. I pay my Clark Rifles dues each year but those guys must wonder who I am on their books.

To the topic: Goodgrouper, yeah, I guess you're right, but isn't it more a problem that comes of benchrest experimentation where a reamer is spec'd short to the shoulder for all good reasons so that the chamber is effectively shortened from any standard and making a die that's made to the standard not able to push the shoulder?

Has the problem you describe been contained to 6ppc? It would be hard for me to imagine that the die makers, particularly Redding, were making dies that vary one to the next, so any issue that arose would be more likely the characteristics of individual barrels/chambers, No?

That guy didn't strike me as a benchrest shooter but maybe he was -anyone know a "Jim Cullen" in Wisconsin? The name sounds somehow familiar to me, but my wife thinks it was the name of some game show host on TV that I'm remembering.
Either way it's a fine point and I knew when I wrote that listing that there might be confusion so I included a link to Redding's site and tried to be as clear as my stupid self could be. Yet that guy insists on trying to mess up my ability to get rid of my old stuff? Over a use of the term 'shoulder bumping' sizer die?

I don't think I owned that die more than a month before I had a reamer made and sent some cases from both of my rifles to the Harrell's brothers and had sizers cut by them to work with my chambers. Not long after that I moved to hand dies. It all took place more than ten years ago so my memory is vague on it all, and I told the guy all of this.

Takes all kinds, I know, but someone tell me why ebay collects so many of the 'dick' kinds? If I had another one I'd list it in here for maybe $20. and someone would appreciate the good deal.

6ppc's are held to a better tolerance but as far as headspace is concerned, it really is no different than anything else. They can still be too long if the reamer is run in too deep, and they can be short if the reamer is short.

In my earlier post, two of the total were 6ppc's. The rest varied from 270 wsm's to 7mm rem mags to 300 ultras and lots inbetween.

I suspect that the chambers are more at fault then the die manufacturers but either can produce error in their dimensions. If Remchester is trying to crank out xxx amount of barrels per day, it can be quite easy to make a few longer or shorter than what Redding's specs are "windowed" for. But again, it could go the other way around too.

A redding Type S 6ppc small base die is made to perfectly size a 6ppc chamber that is based on the standard JGS1045 reamer. No variation of this print has been proven to work better than the original. Most variations are just in neck thickness.

aRRRGH! Setting up a die in a press as if they are precision instuments, i.e, turn just so far plus exacty 90 degrees past some poorly defined point, or using some magic shell holders, unless the ducks are flying east, etc, is a sure way for messing up. Why not just set a size die the way it needs to be set?

Realize that a quarter turn of a 14 threads to the inch die is some .016", and that's pretty large guys. It means you have to take some of that compression out of the slack in the lever-to-ram linkage and spring the press body for the rest of it. Why do that, especially since we don't have any idea of how much the shoulder ACTUALLY NEEDS to be set back?

Get some way to find out EXACTLY where the shoulder of a fired case is, the RCBS Precision Case Mic is perhaps the simplest but others exist. Using whatever you chose, measure where the fired case shoulder is and adjust the FL die to set the shoulder back about .002", no more.

Forget the "turn here and then turn some over there" crap, please!
