Home Forums Reloading Varmint Rifles What stage of brass prep do you neck turn?

Hi guys.
I acquired a forster outside neck turning tool from an estate. At what stage of the prep process do you neck turn?
Before or after sizing?
Also, if i have prepped brass ready to prime and load, can i neck turn and just start loading?

Thanks
Rob

trim to length after resizing, deburr and then turn.

I'd say before sizing. I got an inside neck reamer when I got my 6,5x06 and tried reaming after sizing. Bullet's fell right down into the case! make's me think that you change the diminution of the neck it should be done before sizing! Then bringing it back over the expanding die shouldn't bother a thing.

inside reamers and outside turners are different critters, and don't operate on the same principles. When all else fails, read the frigging directions..... Then you'd see for yourself how it is supposed to be done.

Ok. Thanks guys.
The instructions weren't in the box.

I don't have a Forster neck turner mine is a Sinclair and apparently Forster does it a bit different, with a Sinclair you have 2 mandrels, one is .001" larger that you use to size the neck before you use the smaller mandrel to turn the neck. Forster uses a pilot to turn the necks with, you might have to call them for info

The instructions are available for download on the Forster site.

Forster uses a mandrel to size the neck also, the tool itself has a pilot sized to the neck. You're supposed to run the mandrel in the case which makes it the right diameter and perfectly round. After using the mandrel you neck turn.

If I'm going to neck turn new brass I do it first thing. I run the mandrel in the new case, neck turn, then chamfer and size the case. It has to be resized after neck turning to return the neck to the proper dimensions.
