Re: Redding Match Dies - Which ones?

These shell holders are set up in .002 heights to allow you to set up your die so that you just barely bump the shoulder each time. Since I'm loading to hunt, I did not want to get a sticky bolt close like often occurs with neck sizing dies. I'm also loading "hot" loads, so my resizing step lets my brass be "sized" for proper chambering without fighting it. I've been very happy with this set up.
[/ QUOTE ]wapiti13, I looked for those shell holders on the website. Do you mean that they get progressively taller in .002 increments?

Ernie, there is nothing wrong with conventional full-length sizing dies used properly for bottleneck cases. The only thing that might be done to one is to remove the decapping pin and ball then lap the neck out to a few thousandths of an inch smaller than a loaded round's neck diameter. Deprime fired cases in another die then clean 'em before lubing and sizing 'em.
Believe it or not, this type of full-length sizing die can produce excellent accuracy. They make the straightest cases 'cause there's no expander ball to bend the case neck. It is important that the fired case's shoulder be set back a couple thousandths from its fired position; that's about to the same position a new case has. Such sizing techniques can load the same rimless bottleneck dozens of times; 50 to 100 depending on how much the case body is reduced. This method is used by virtually all the top highpower rifle competitors who win the short- and long-range matches and set records doing it. The accuracy attained equals what the benchresters get. And many benchresters are starting to use this same method.
In my opinion, neck sizing is what people do when they don't properly full-length size a bottleneck case. Fortunately, most people can learn how to do it.
[/ QUOTE ]Bart, I'm confused. How do you lap the inside of a neck die smaller than a loaded rounds neck diameter? I would think the ID of the die neck would become larger which means less tension on the case neck to hold the bullet. I neck-size only for a factory 222, 22-250 and 308 and have not had chambering problems. Once in awhile the bolt closes a bit more snug but that's it. Maybe that's the difference between a factory and match chamber. I thought the entire deal was to neck-size only and don't touch the shoulder which ensures the brass fits to your chamber.
I was looking at switching to Lapua brass and getting Type-S neck dies for those calibers mentioned above.
Would you recommend a FL type-S die without resizing button and the appropriate neck bushing? I believe the FL die will still allow me to neck-size only.
Btw, if I sound confused.... I am LOL
Ernie, didn't mean to hijack your thread but you started a good topic here. Thanks.
