I like Forster

 

[CF Junkie]

+1 for Forster. They adjust 25 thousandths per rotation.
I also have an RCBS micrometer it adjusts 50 thousandths per rotation.
I find the adjustments easier with the larger increments on the micrometer.

I agree with CF Junkie but one nice thing with the RCBS is the side loading window. Quite convenient

LE Wilson SS Micrometer inline are my favorite to use with my K&M Arbor. I have lots of Forster and Redding and others collecting dust.

I’ll get my chops busted, but I like the Hornady click adjustable top micrometer for their seating dies. I can hear and feel the one thousandth clicks easily.

I’ve just recently started using Wilson inline w/arbor press but if I were looking for a standard press type seating die, it would be Micron.

Here are some of the “best” micrometer seaters I’ve been using, Micron is the most consistent and does not introduce any runout if that matters

I can see why, look at those seating stems!

and no set screws of any kind to introduce runout

I like my Whidden.

+1 for Forster micrometer seater.

I’ll get my chops busted, but I like the Hornady click adjustable top micrometer for their seating dies. I can hear and feel the one thousandth clicks easily.

Years ago I did a test, comparing 6PPC loaded round straightness produced by a Hornady seater, and a Wilson. The cases had the same runout. The runout for the Hornady round was twice that of the Wilson. Admittedly this was the smallest possible sample, but I was familiar with what my usual results were for the Wilson. The most finely fitted seater that I own is one made by Don Nielson, it fits much more closely than any other, and is specific to a .262 neck 6PPC chamber. Since no micrometer is available for it, I learned to adjust it by the overall length of the stem and cap. Since then, for arbor press dies, that is my preferred method of adjustment.

I use a non micro L.E. Wilson seater and a feeler gauge.

The Microns are things of beauty. I've not yet had the pleasure of using one, as the Wilson micrometers have been doing a fine job, as have the Forsters, but I doubt I'll be able to resist much longer . . .

I should have added, Threaded to my question.

I have two Forster threaded dies I have used for decades now, one has loosened its threads so I was interested in something better if I can find one. Still have Nursing Home Money to get shed of .

I gave up on Arbor dies years ago because I never found consistency in using them. I measure every loaded round from where the ogive slope begins to the butt of the case and have never found that press dies will give exact loaded rounds. That may not be the total fault of the die solely as bullets vary a lot when one gets to that nitty gritty measurement, because of the length of the slope to the tip of the bullet.

I switched to a turret press and a threaded dies so I can use a bullet puller, dial up the difference I want and adjust to zeros.

Getting back to the tollerance question: if one doesn't insure each bullet will strike the lands at the same exact place every time, well ------- . So the threaded die allows for the easy adjustments.

So, who is making the best threaded Seater die?

Thanks,

Pete

I use custom bullets, Micron seating dies and AMP press and there's hardly any variation B to O, recently loaded 200 rounds for a match and found two or three rounds where B to O was off by .001"
So if uniformity and precision is what you're looking for a quality components and tools are critical IMO
