Redding dies

rgitzlaff · October 17, 2006, 07:28 PM

Currently I reload for my 7mm Rem Mag with a set of Lee dies. I neck size only. I have a line on a set of Redding dies, which I'm told are just about top of the line. The sizing die is full length. Are these dies adjustable so I don't size the whole case, and just the neck? I have heard people talk about how they just bump the shoulder back a couple thousandths each time they size. Thanks.

I use a Redding neck sizer for British .303. It is a wonderful die, can't go wrong with it. Couldn't tell you about the FL sizer die used in that application. I did get a good deal on my die from Midway if that helps.....

"...adjustable so I don't..." Yep. You set up the die so it neck sizes only. Takes a bit of trial and error to get them just right. Same as any other die set. Mind you, if you're getting good accuracy with the Lee dies, why are you changing dies? Rule number one applies. If it works, don't fix it.
Redding dies are just dies. They work as well as any other manufacturer's dies. There's nothing special about them.

Special NECK SIZING DIES
I E-Mailed RCBS on December 12, 2004 and received the following response on December 15, 2004.

From an old #8 Speer Reloading Manual. You and other equipment manufacturers sell special NECK SIZING dies. Does this still apply to your equipment?

Neck Sizing is the term applied to the process of sizing only the neck of a case, with a special die which doesn’t touch the shoulder or body of the case. Neck sizing does eliminate excessive working of the case shoulder and body but, also, may size the neck off-center and leave the body of the case too large to chamber. A better way to reduce excessive working of the case body and shoulder metal is to use a full length sizing die but, use it so it only sizes partially. To do this, the full length sizing die is backed out of the tool so that the shoulder is not touched by the die. This preserves the important head and shoulder dimension and still sizes the neck normally. The body of the case centers the neck in the die and is sized enough to make chambering fairly easy in a bolt action.
Back the die off at least 1/16th of an inch [About one complete turn.]
Many shooters adjust their dies so that only half of the neck is sized. This leaves enough tension to hold the bullet securely for target or varment shooting

The RCBS “Ask the Expert Forum’s response was:
Yes, the necksizers only size the neck of the cases. And yes, there can be run-out after necksizing as there is nothing to support the base of the case - it just sizes the neck. AS FOR PARTIAL SIZING -- Many of our customers choose to do this - but, it is trial and error and sometimes the chamber v.s. die fit does not allow the reloader to partial size - they will not chamber afterwards.
