So I picked up a savage 12fp, I decided I want to neck size only. I also decided I want to have less neck tension than my rcbs dies are giving me. Are the Redding dies the only ones you can change your sizing diameter to alter your neck tension?
Looks like my RCBS are giving me .004" of neck tension, I want to get to .002" or 0.0015", whose dies can do this? |

Measure often with a caliper, you can't put metal back on. |

I haven't yet used my Lee neck-sizing die, but if I'm not mistaken, its a collet die, and its infinitely adjustable. So you can basically adjust it for anything without having to buy new bushings. The lee Collete sizing mandrel is .222" and you have to size the brass all the way against the mandrel to get a consistent ID neck size, so no they are not adjustable. I have the Hornady Custom Comp FL neck sizing die and it sizes the base of the brass way to much, to the point to where the brass flows up and gives inconsistent headspace measurements, if your not using FL then you may be OK and you can use Redding and Wilson bushings in the Hornady die as well to get .001" sizes. I just got my Redding Type S FL neck sizing die and love it, it sizes the base barley but just enough and with the Nitride bushings sizing is almost effortless, their bushings run about .0015" so if you want 1.5 thou. neck tension get the bushing that is .001" under the neck size of your loaded rounds and you will be golden.

| I started off with a LEE Collet die and decided after a short period that their was a better way especially for the high dollar Lapua brass my wife got me for Xmas so i ordered a Redding S type set with the bushing, yes it's alittle $$$ but so is brass and it's very consistent, if you stay with the LEE collet you can purchase different mandrels from LEE |

You can buy a Forster neck sizing die in the caliber you need. If it sizes the neck more than you want, ship it back to Forster with your Credit Card # and they will hone the interior to any dimension you desire. The cost for this custom service is a mere $10.00 plus shipping.
Simply state in the package the exact neck size you want it honed to such as 338" or .337". I believe this service makes Forster my favorite die company right now. Measure a loaded rounds neck and subtract .002" for .001" tension after spring back. Subtract .003" to achieve close to .002" tension after spring back. I don't think they will hone to the tenths, you could ask for .0025" less than your measured neck, that would get you .0015" neck tension. |

This would be no good for brass with varying neck thickness, you would have to neck turn all your brass to the same thickness for this to be right all the time, doesn't sound like a very good solution when you can just get a bushing die and a few bushings to cover what ever neck thickness the brass is your working with at that time. |
