Neck Sizing Problem

[Klenchblaize]

I have three sets of Redding neck bushing dies (6.5X55. 222. K250) that have been faultless and allow full neck sizing coverage down to shoulder juncture.

Recently started reloading for a 6mm PPC (US) with a Redding bushing die but no matter how I adjust the die and check my staged sizing has set the shoulder back correctly it is impossible to size more than 3/4 of the neck! That this juncture happens to correspond with where the base of the 74g Berger sits within the neck may suggest all is well but it looks all wrong to my eyes and sensibilities.

Any suggestions please short of reverting to use of a conventional FL die?

Thanks

Not trying to teach you to suck eggs , is it possible the bushing is incorrectly orientated ?

There was another thread on here a while ago with the same issue, wad it the bushing the wrong way up?

 

[Klenchblaize]

I’ve taken critical measurements with it both ways up and the differences do not translate to the degree of un-sized neck.

Sounds like there is a mis-match between the brass and die dimensions.

Try sooting your cases and see where is hitting, I suspect a quick pass of the appropriate reamer would sort it.

Is there not a longer neck to contend with anyhow ? Sounds like you might simply have the wrong bushing type or part for the job .

I’ve reloaded the 6 PPC & 22 PPC for several benchrest rifles using a die by Harrells Precision which sizes the case body & neck using a bushing (by Redding/Wilson/Sinclair etc) - effectively the same as the Redding S dies.

The Harrell die sized the neck down to the shoulder if required.

I find that my Redding S dies for other cartridges don’t size quite as closely to the shoulder as the Harrells did but I find it strange that your Redding PPC die only allows 3/4 of the neck to the sized. It may just be a quirk of the Redding dies for that cartridge or for some reason the counterbore for the bushing isn’t quite deep enough on your die (again I’d be surprised if Reddings quality control was lacking but things happen).

You may like to try the Harrells version.

Full Length Die

It's not the first time I've experienced Redding dies to only size a portion of the neck before it goes no further.
It's happened in a few different cartridges, mainly competition biased cartridges.

Mines the same but the bullet only sits within the sized portion of the neck so I’m not worried. 0.1-0.2 MOA so it’s not a issue tbh

Is the decapping rod set too low ?

I removed the decapping rod as I do all my de-priming as as separate and initial process.

The only way I’m going to get more of the neck sized is to get the case (shoulder) closer to the bushing and that will me mean removing internal die metal.

Thanks for everyone’s input.

I know your an experienced chap so apologies before hand. Trying to understand why you can't full beck size with the bushing die. I've used redding comp bushing dies for nearly 20 years and can't see why you can't lower the bush. Is it at full length, i set mine up to give me max length possible to resize the neck, is the die set up to achieve this ?

K - I have the same issue with the Type S neck bushing die in 222 Rem. Die is in contact with the top of the shell holder & bushing is set as low as it’ll go in the neck with packing washers above it to stop it rising as the neck enters. As already been mentioned, bullet only seats into the sized portion of the neck so no dramas, just looks strange.

Consider milling the shell holder some?

 

[DVS1]

Not 100% certain it will do what you want but perhaps match shell holders so you can incrementally adjust the depth etc? Only say this due to post above...I could be waaaaay off base lol

This as approach won’t permit the case shoulder to move forward of the die abutment point.

Such an approach will however work with Lee Factory Crimp Dies if you trim your brass more than SAMMI.

My S type die in .222 showed similar issues, strange. Use one for my .223 and sizes the whole neck.

Or a different shell holder, perhaps?
Redding do sets.

 

[kenbro]

FL size then use expander mandrel?

Perhaps the following will better explain the determining factor in neck to bushing contact:

Once the case shoulder has contacted the walls of the mock floating chamber it cannot be forced any further towards the bushing by either machining the base of the die or shell holder. Only removal of metal at the points indicated will address the issue.
