Micrometer adjustment seating die. Cheap. I may get one just because. Cartridge specific, unlike Hornady which is caliber specific.
It’s honestly NOT much more expensive to make a die micrometer adjust. It’s just a matter of making the seating adjuster 40 threads per inch rather than some more common thread. One full rotation would equal .100, so that the .001 marks coincide.
Might be handy for my .300 blackout. I’ll save the Hornady die set up for my Barnes loads, and have the Lee for farting around loads.
Cool. I just enabled myself.

Interesting. Pretty inexpensive. I might pick one or two up for a couple cartridges at some point. After you get one and test it..

It’s ordered.

If I was more serious about reloading than just dìckin around, I'd modify my existing dies. What a missed opportunity

You’re waaaaaaayyyy late to that game if you wanted to profit. They’ve been around a long time.

I actually hacked up an import micrometer and put it on a regular seating die. Works perfect.

It’ll be better for when i load up different .300 bullets. Because I know you enjoy shooting it.

Dear Lee,

You come up with this $20 option now when I've had the Reddings for decades.

YOU BASTARRRRRRDS!!

There’s my home built version.

Excellent. Some people might find it to be a waste but it's a pain in the àss when you're OCD, want to get to a specific OAL and have to keep seating, removing, measure... until you finally get it. And it would work great in keeping recorded specs for different loads, bullets, etc...

I have it marked for the two .223 bullets I use. Turn the dial and done.

Enabled..... Will mark for 600 yardline and mag length

My fussy inner machinist is very happy with the quality of this die. Like, very happy.

Now to see how it actually works.

I’m thinking a few of those might come in handy for running on my Dillon 550 press. Much easier and more repeatable than standard seating die’s. The price seems right.

I don’t use my 550 very often. So I transfer my dies to it, adjust everything, then run a couple thousand rounds of general purpose ammo. Then take my dies back out and use them for small batches of more specialized ammo on my other presses until I want to use the 550 again. Having seating measurements on the die could be helpful.

I’ve grown kinda fond of the RCBS Matchmaster seating dies. But cost of those has limited me to only having two of them. 6ARC and 6.5 PRC. For everything else I load, I can’t justify the extra cost.

If lee would come up with a micrometer adjustable copy of the Hornady seating die, they would have something good happening….

Ummmmmmmmmm…..that’s what this is.
Has the same floating seater arrangement as the Hday.

You’re welcome. Need the link ?

Oh crap! I didn’t see it had the floating seater thing… The Hornady one hangs down below the base of the die, so I ASSumed the Lee was a regular seating die with a micrometer adjustment.

Well then… I will probably be ordering a few of these..

AND, you can use it as a "dead length" seater without crimping, or turn the guide over (it screws out the bottom) and then have a crimp capable seater
