Full or neck size

[Greyfox]

Most of my precision reloading for my hunters utilize FL/bushings, but not always. Having used all the various methods over decades of reloading, I do avoid getting sucked into the gross generalities, and "so-called' conventional wisdoms pertaining to the various practices. I will tailor my methods to the particular rifle/chamber, and desired results for the job. Choice/brand of brass is an equally important factor for me.

That's true while using off the shelf FL dies.
I use custom bump dies. They support the body (without sizing), while shoulder bumping only.
Then Wilson bushing NS, and Sinclair mandrel pre-seating.

There are all kinds of dies to do all kinds of sizing.

Using your method do you have to fully FL size every so often for chambering purposes. and are there commercial dies made that just bump the shoulder. TKS

I'm sure you can have custom dies made for this. Forster makes a production bump die that does not size the case

This is the question I can't get an answer to from Forster's literature. How much does their bump die size the body? They don't directly address this, so by omission they seem to be claiming that it doesn't, but even if say it were cut +0.003 as opposed to the -0.003 of their small base die, it would still size the body down to a point.

It's my understanding that the Redding body die is an FL die with everything above the neck removed, so it does resize the body to a standard minimum dimension in addition to moving the shoulder back.

Basically "Dimension A" from this chamber reamer is something that has to be specified in order the get a reamer to cut a die, so what is that dimension? In Redding dies, I think FL and body die it's the same spec. Forster bump die seems would be larger than their FL die, which is in turn larger than their small base die.

Forster die info from the slip sheet, note this is only the 308 specifically because the offer the two special FL die dimensions in addition to standard.:

Bushing Bump Neck Sizing Dies – Forster Products

Order according to the profile of the specific cartridge.

According to Forster:
"This die improves accuracy and prolongs case life because the body of your case maintains its fire-formed "glove" fit to your rifle's chamber. At the same time it "bumps" the shoulder of the case to maintain excellent case neck concentricity."

I don't FL size anything for MY chambers.
Bump dies have to match what a chamber forms. Custom, per the plan.

Most common cartridges and chambers out there will require FL sizing eventually, so bump dies can't help with that.
But a custom FL die can still help.
