Happy NEW YEAR guys.
Actually any sizing die can do that. It is all in how you adjust it. Most advise, in their instructions, to have the size die touch the shell holder, then back it off at least 1/4 turn and work from there to have the case offer pressure on closing
the bolt.

Default Different dimensions..





According to these diagrams, the 17FB is slightly larger in dimensions at the shoulder and the case body length.

I guess I can just use the 17MKIV dies, but its overworking the brass at the shoulder and is causing cases to stretch just ahead of the case web.

I was just trying to prevent this from happening.

Spin your MKIV die up far enough you are only sizing the neck about 2/3s-3/4 of the way down the neck. No more overworking the case body and as long as the brass is used in the same gun it will work fine.

First off, the size of the rifles chamber is the wild card as to how much any die 'works' the brass.

My recommendation is for the Redding Type 'S' full length sizing die. These use a bushing to control how much you reduce the neck diameter...no more over sizing the neck like in a conventional full length die, then jerking it back larger as you pull the case neck off the mandrel when you size it. The less you work the case necks, especially on the .17's, the better off you are. Plus, there's no more lubing the inside of the necks with the bushing style die.

You'll need to precisely measure the neck diameter of one of your cases (with a seated bullet) to determine what bushing(s) you'll need. Also, the dimension of the neck of a fired case is valuable to have...sometimes factory rifles have such big neck diameters that an intermediate bushing size is needed before the final bushing (to reduce runout).

For a seater, a conventional Redding seater works fine. If you're looking for a seater that's a step up, a Wilson inline seater and a small arbor press works great. Redding and others make a micrometer adjustable seater if you don't want to go the inline seater/arbor press route.

If you want to stay real basic, the bread and butter Redding two die set would be my recommendation.

In closing, based on experiences, my recommendation is:

(1) Redding #77204 (full length bushing die) & Wilson #BS17-RFB seater)
(2) Redding #36204 (full length bushing die & micrometer seater)
(3) Redding #80204 (conventional two die set-f.l. sizer & seater)

A quick check showed several of the online sources having these in stock as of today. Just sayin.....

Good shootin'. -Al

This might work. Thanks, I will try it.

Why don't you lube the insides of the necks when you use a bushing style die? That is the first time I have heard that, but I like the sound of it
