Guess I’ve got enough firings, 4-5, on this brass (ADG 6.5 prc, known for doing this) to finally get some clickers. I’d rather not trash it, but my Redding S dies obviously aren’t sizing down far enough. What’s the best solution here to size down the base only?

Before someone says it, I don’t want to go grinding down my shell holders.

ya know, I ended up being given some 6.5 x 55 brass that a friend down in California was necking up and Shooting out of a Swiss Cartridge chambered rifle... 7.5 x 55? maybe.

it was once fired brass. I brought it home... lubed it to size it, in my usual method of spray lubing a camp frying pan ( bought 20 plus year ago for $6.00 ), putting brass in and shaking it like the old Jiffy Pop popcorn . It lubes the brass up, both cheaply and also with a lot less mess than other methods.

Put the brass in my sizing die and lifting the handle, it was like trying to neck down a cinderblock into a cartridge.

Well screw that, so I set it aside in a butter container ( plastic like you get at the store, Country Crock ). It sat on the counter for a couple of weeks. So one night before I came back in from the garage after doing so other reloading, I saw it and thought, "What the hell?". So I pulled out on of the 6.5 x 55 dies, and it sized just like new brass never fired does.
I thought 'what the hell again" Well all 50 pieces sized right down. Conclusion? Guess the oil penetrates the hardness of the brass, and softens it up.

Have since, done the same thing on other brass and that works just the same way.

so if you aren't in a rush.....

Also I anneal my brass pretty much each time nowadays... at least 90% of the time. That also helps keep the necks and shoulder of the brass from hardening.

I get a lot of firings out of my brass, than most folks would believe. A little prudence on the reloading scale also helps extend brass life a lot. NOT trying to get ever last FPS out of a case each time ya use it. Back it off 5 or 10%, it'll last a lot longer, with the annealing etc.

Give it a try and see if it works for you also. Sure beats just trashing it and then have to look for some more to replace it at today's prices.

The Cortina mandrel die will size down on the 6.5 PRC a bit further. The other option is Cortina's FL sizer die designed for the smaller chambers. The true ultimate fix is to have the chamber reamed. Check out Alex Wheeler's comments on the subject.

My ADG brass has 8-9 firings on it and maybe one or two pieces out of 50 results in clickers with just the Cortina mandrel die. All still have good, tight primer pockets.

You AMAZINGLY Stupid Fhuqks,never disappoint. Hint.



Thank me later. Hint.

Just sayin'.............

We can only wish that people would learn what Competition Shellholders actually do to brass, before they recommend them to size brass down further than a standard shell holder... They will not work...

Don't listen to that stupid-ass advice from Betty Sue. Competition shell holders are designed to control shoulder bump, not size further down the case. You cannot isolate the dimensions from one another. You'll end up moving your shoulder back too far, and it still won't solve clickers. In fact, moving the shoulder back to far can make it even worse because the brass tends to flow around the .200" line as the shoulders expand to refill that headspace gap you created because you pushed those shoulders back further.

Get the mandrel die, or have a smith fix your chamber.

My wild idea to size the base down to .530 would be to run the brass through a 500S&W carbide sizer, that sizer should size the case back down to .530. Haven't tried it yet, work & life have gotten in the way, but I believe it would work.

Ladies,

Your Drooling Dumbfhuqktitude,NEVER disappoints. Hint.

Fhuqking LAUGHING!..............

For pete's sake, it even states the purpose of the set in Redding's own description, but Betty Sue can't read.



Poor thing, probably hasn't loaded a piece of 6.5 PRC brass enough times to discover the problem and she doesn't understand the purpose of Redding Competition shell holders, nor what the issue is. Parallax, scope mounting, and now shell holders...Betty Sue is in dire need of a win.

Ladies,

Here's to the HILARITY of your Automatic Transmissions,Velcro laces and affinity to steal pictures and punctuation. Hint.

Deck height/base sizing is an easy cure,less effecting headspace,if only to your chagrin. Hint.

Fhuqking LAUGHING!..............

Betty Sue, you should learn when you're conquered. You don't know what you're talking about yet again. Share with the class how many times you've had "clickers" with 6.5 PRC brass? Hmmm. But that's cute, Betty Sue, you think you're smarter than Alex Wheeler. It is funny how schizos laugh when they are confused.

Sweetheart,

You are the one asking questions and trying to cite others...not me. Hint.

Fhuqking LAUGHING!..............

Betty Sue, Betty Sue...for every increment further your FL die sizes, the shoulder pushed equally as far. This is stupid and not the cure. With the taper of the 6.5 PRC case, or lack thereof, you cannot solve it in this manner. You'll only create extra headspace and compound the problem. But you lack the experience. I've already provided the solution to the OP. Now go change your pad.

Sweetheart,

I didn't cite or state your Fhuqking STUPID die selection,you did,based on your "abilities" and "comprehension". Hint.

No... drop_point.....

those shell holders size the case less and less by increments of 0.002"... the case becomes longer and longer by less and less sizing when going from +0.002" to +0.010' shell holders... This will create other problems not even discussed nor considered here.. Competition Shellholders are not the solution to this problem....

Correct, they allow for a hard stop on the shell holder while incrementally increasing length to the shoulder.

A properly dimensioned chamber reamer is best, but base sizing with a carbide pistol die, or a custom ring die could help.

You Drooling DUMB Fhuqks are a HOOT! Hint.

The FIRST fhuqking move is to Cerrosafe the chamber and KNOW,what the fhuqk is going on. Hint.

Not that I don't enjoy the quotes,lathes and fhuqking STUPIDITY espoused. Hint.

Fhuqking LAUGHING!.................

Throw it in the trash and buy some Peterson brass. Problem SOLVED

The set doesn't include a "0.000." what is the +0.002 in reference to? Its a hypothetical.

They fall on both sides of basic "shell holders", depending on how you set your die. With your average shell holder, you could be anywhere within a few thousandths. Compared to my generic height RCBS, it falls around the same as the +0.004. Tolerances and brand differences matter as well.

If you need a set, step it up a notch and get the Area 419 set which includes a -0.002 up to a +0.008".

Betty Sue suggested using them to size further down the cartridge. There is no cheating it; sizing further down the brass toward the .200 line also means the shoulder will be pushed back further. It cannot be achieved any other way with the die he has using the Redding competition set. Which is why it doesn't work. He either should check out the Cortina Mandrel or have his chamber fixed.

Tell me you have zero experience with the 6.5 PRC without telling me you have zero experience with 6.5 PRC.


If you have SAAMI-spec chamber, this happens. The solution is a non-SAAMI reamer or another die. You keep laughing because your schizophrenia is getting the best of you, but you forgot to change your pad again.

Right, i’m fully aware. Which is why I said I didn’t want to grind down my shell holders. Got a Cortina mandrel die on the way. Thanks.

I got a couple hundred pieces of 3-4x fired ADG so it should still have some life in it once the base is re sized, but has anybody really had better results with Peterson or Lapua?

Hopefully it works for you, I run mine through it twice.

""The set doesn't include a "0.000." what is the +0.002 in reference to? Its a hypothetical."""

the +0.002" shell holder is referenced to a standard shell holder which is almost always 0.125" (which would be considered a 0.000" holder)....... they get progressively taller deck height by +0.002"....

PRC: Too much of a good thing..

Have you measured the "standard" shell holder? There is quite a bit of variance.
