neck sizing and trimming question

[Witch Hunter]

New brass or range brass, treat it all the same. Full length size, trim, uniform primer pockets, deburr flash holes. turn necks to make concentric only. Hand prime, charge, seat bullet,(no crimp) shoot. Now, neck size, trim, load and shoot. Repeat until A: primer pockets get loose when priming(use a hand primer to notice) or B: necks split. there is a lot more(seating depth) but this is a basic bolt action process after you know your load recipe.

Depending on your chamber you may need to squeeze the case back down to dimension. This may not bump the shoulder. But as you squeeze the base of the case back down to size, the case length grows. The brass has to move somewhere.
The redding body die is perfect for this.

I'm pretty sure you can send fired cases to Wilson and they can make you a custom one.

oh really?

hmmm sounds extremely tempting

Using them as body gauges wont do you any good anyways.

Not sure if either one of you have ever tried a Wilson gauge, they are already oversized.

I have no issues fitting fired brass in my gauges.

I like neck sizing my bolt brass with Lee Collet dies. Fast, no lube, adjustable neck tension. There's a bunch of other operations as listed above if you're shooting for benchrest competition accuracy. Choose which ones fit your needs/desires/willingness.

+1 on Lee collet dies.

I never thought the cheapest most simple option would deliver such fantastic results... good enough for my purposes and with minimal case prep to boot.

did you neck size and trim?
or just neck sized and decapped and then loaded them up?

Decapped, clean, neck size, trim, prime, powder, seat

Decapped, clean, neck size, trim, prime, powder, seat

gotcha
I'm going to try that formula out next time I process my brass

It's for my r700
I'm trying out neck sizing because it's "suppose" to make you more accurate

But ive talked to many other precision shooters and they said just FL size everytime by just bumping the shoulders back 0.001 to 0.002 thousandth

Can anyone recommend me a GOOD FL die that will also be consistent with neck tension?

The redding Type-S Full-Length die with a proper neck sizing bushing is where it's at.

The die only sizes 2/3 of the neck length and swappable bushings allow you to TUNE your neck tension.
The die leaves a little donut to center your cases in the chamber like a neck sized case, but without the case body dimension issues of neck sizing...

Remington chambers will accept cases as long as 2.045", do u don't need to trim these.
