Factory honed neck dimensions on dies rock!

After collecting a number of Redding Type S full length and neck sizer dies with bushings, I think I've found something I like much better.

I recently began playing around with some Forster and Redding dies where I had the factory hone the necks on standard dies to a particular diameter. I'm finding that my case concentricity is improved and I do not have the whole double shoulder that is often created with bushing inserts. It is also easier to dispense with the center rod and neck inside sizer bead as well reducing inside neck galling, reducing case stretch, and improving concentricity.

I believe in time this may also reduce the incidence of donuts on particular cases I've loaded. Time will tell. Since I don't need much variability with my loads that are tweaked, these end up being an almost perfect solution and at $10 for Forster Benchrest dies and $20 for Redding standard dies, you actually end up saving money! Heck, if you need varying neck diameters, you can practically buy two dies for the price of 1 die with bushings (and all the cons of the bushing die).

Have any of you gone this route yet? What are your experiences? So far I've been pretty happy with the test and may continue converting other die sets.
 
Re: Factory honed neck dimensions on dies rock!

I took one of my old RCBS neck dies to my smith and asked if he could open the neck to a custom dimension... I was thinking along the same lines. Toss the expander ball. He said they were far too hard to machine. I was unaware the factories offered this.

I've done this and got similar results, but in a different way. I ordered RCBS inside neck ream dies with a specified neck diameter. Much better concentricity.
