I am leaning toward a new Dillon 550b, but what powder measure works best for extruded powders. I had a 450 and it's powder measure was varying almost every powder dump, sometimes as much as a grain. So what works with extruded powder and a Dillon 550.

Cost as much as a Dillon but the JDS Quick Measure and press adapter is best extruded PM available for press mounting. With amazing consistency it tames the logs extruded powder like IMR4350. It's kind of a pain to to set up. Keeping notes used to obtain the desired results is necessary.

If you want to maintain the auto drop feature Hornady makes a set up to mount a rotary in place of the Dillon. On my 650 I use for rifle loading I made a powder measure stand tat positions the measure over the powder die. I mount a Harrels there. The draw back is it is manual you have to cycle it every time.
My Dillon measures do pretty well with some stick powders. Keep it clean and working free.

At least with the short stick extruded pistol powders like the Vihtavouri N3XX series, I get literally "good to the last drop" repeatable drops to a tenth of a grain with just the standard Dillon measure.

Consistency in the operation of the press has a lot to do with it, I can get my 550 to drop 4064 at no greater variance than .2grn

The best measure is this:

The 2nd best for stick powders (drum roll) is the current Lee.

....I am leaning toward a new Dillon 550b, but what powder measure works best for extruded powders....

We would all like to buy certain products that assure success but ..."best" is a relative term.

Fact is, no volumetric metering device can ever be precisely refilled time after time with anything but liquids. Small powder kernels measure pretty well, larger kernels not so well and any differences between brands is, IMHO, too little and unpredictable to matter. All popular measures work and user consistency matters more than brand or price. Press mounted automated powder measure drops from turrets or progressive press is perhaps the least consistent of all.

To get better uniformity from your measure will require (1) dropping each charge low and trickling it up OR (2) use an electric measure with built-in trickler/digital scale functions to accomplish the same thing OR (3) develop new loads with smaller grained powders that meter well.

JDS Quick-Measure works well w/ all powders, even stick.

I've gotten +/- tenth grain accuracy out of my Lee PPM with IMR 4831. But I still check every charge and trickle if it's off.

We used to to shoot M1 Garands quite a bit plinking more than target shooting for them + or - a tenth on a 55 grain charge made no difference we could see and we were 5 grains from max
On the loads for guns we wanted the best from or near max from the book like MrHarmless we always trickle up to the weight we want.

I've bad experiences with all the rotary measures. Love my Dillon, Quinetics, & the old Redding model with the measure tube that comes out of the body bottom; used correctly it measures 4831 & coarser with in 0.2 gr. I had RCBS LiL, Lee auto, Lyman, CH, & RBCS rotary; all were traded off. I've not been able to try a Belding & Mull just yet. But I suspect the Redding with beat it out.
Granted consistent motion is a factor in the accuracy of any I've used, but the ones I mentioned make it a lot easier.

I have used just about every powder measure out their and the best I ever used for stick powder is the lee.
