Does anybody have one? Good,bad?

I guess they never sold any?

I have one, but I'm using my Harrel and haven't even unpacked it yet.

I don't use a 10X but have a 3BR and a BR-30. the BR-30 and 10X are the same except for the charge capacity range. My experience with it ( and the 3BR) is positive. It is very consistent from charge to charge. However I think that 50% of the battle with any powder measure is technique.

What is your intended use? The 10X is designed to only throw charges of 20 or 25 grains max. My BR-30 will go up to around 50 grains depending on the powder. If your doing something very specific like throwing charges for a 22 Hornet or want a dedicated pistol measure it would serve you well. Otherwise I would look into the BR-30 since it will give you more versatility with respect to powder charge range.

I have a 10X, does a very good job of metering a load of 1.8 grains of titegroup for 32 long's. I don't know of any other powder measures that will meter such a small charge accurately. And as David pointed out, the 10X isn't intended for loading large rifle cartridges, but is great for little pistol cartridges like the 32 long, and I suppose the 25 and 32 ACP's but I haven't any experience with them.

I am very happy with my BR-30.

I polished out the powder chamber just for fun.

I always wipe down the plastic with an anti-static cloth.

The 10X is about as good as my baby sized Harrells, and that is very, very good.
