Does anyone know where I can pick up a neck sizing dies for my .375 CT?

I am full length re-sizing and would like to try neck sizing only to try to improve my groups. The fired rounds re-chamber so I may get by with neck sizing.

Mine is an "Improved" version with very little taper so long before I get to a point of bumping the shoulder I am already putting the squeeze on the body of the casing.

I will have to back off until I don't feel the resistance of resizing the case body and and assess how much neck sizing I am getting. You may be right and I can get by.

Call CH4D - they'll have pretty quick turnaround times on custom dies and make a bushing neck sizer that I used in my .408 for a few years.

Thanks Dogtown,

I called them a couple years back on dies for my 375 CT but the wait was too long so I went another route. I will give them a call on this.

My brass is neck turned to .0145 wall and I want .002 squeeze so I have an ID for the die. I am having slight concentricity issues and am looking for something that can center the case as the neck is sized.

Any suggestions to correct runout? I have a Sinclair concentricity gauge but once I identify the runout it is a little tricky getting the round trued up.
