Pressure ring and seating depth

[chino69]

Does it matter where the pressure ring is in relation to the portion of the neck that is sized?

Example: I use a Wilson neck sizer that sizes a portion of the neck. If the pressure ring of the bullet seats within this sized portion of the neck there will be an annulus between the od of the pressure ring and the id of the neck sized area; a very small void. The question is, does this affect accuracy?

Is it more desireable to seat the bullet beyond the neck sized portion, that is down toward the shoulder where the void would be minimal?

I realize most seat their bullets into the lands or beyond so this question would be moot but the question remains, nonetheless.

Any answers would be greatly appreciated.

Doesn't matter

If you seat the pressure ring (as it's called) below the sized part, the bullet will fall in when the neck hardens. That's not a problem either given the availability of smaller bushings. When they start falling in you can just pull them back out or give them a "sling" as you load and shoot. One would think such a thing is detrimental but I assure you it is not.

Conventional wisdom is that the pressure ring should be in the sized portion of the neck. Back when I was neck sizing (a long time ago) my setup was that way and I could detect no ill effects. Having the pressure ring behind the sized portion reduces the avalible neck tension, because you have passed a larger diameter through that portion of the neck,, stretching the ID slightly. On the other hand, anything that works at the target is OK.
