Is an add on Micrometer top from Brownells to
a Wison die, a good investment ???
I’m going to do one in 6mm in a few months. Buy it and if you don’t love it I’ll buy it off of you.
I like them.
I check distance to lands after each shooting session with a stripped bolt and they make it quick and easy to adjust your die for touch. They certainly aren’t necessary but I wouldn’t be without one now.
I have them on all mine that dont come standard with it.
It enables you to return to the precise same seating depth that your test load excelled at. Worth several times more than what they cost.
I have them on every Wilson.
I feel like you're being misled about it's application accuracy though..
You cannot simply 'dial in' seated CBTO.
Like many things in reloading, seating results are never right until verified so with measure(each one).
Regardless of any die setting, CBTO is affected by seating force/stem wedging and ogive radius variances for each bullet seated. So while you can dial the seating stem down per scale, the bullet is unlikely to follow that scale in a linear fashion.
Dialing is useful, giving you a starting point and adjustment for each round. But don't assume adjustments are accurate. Measure them, and tweak into desired.
They are ok but they upset easy with the weight on top. I went back to the shims..... Jim
I like mine, but...The Wilson/Sinclair micrometer top seater die is a definite step up. Guys bitch about the cost, but I don’t know. It is easier to control with precise clicks and no set screw. Seating adjustments and return repeatability are really good. Wish I could get one of those in a blank where my smith could run my reamer in. I asked. Wilson said no. Can’t blame a guy for trying.
Not sure why you cant get a micrometer blank. I just did one for @JRS . Didnt even have to beg- it was in stock
That's not it. The micrometer top on those is a step down. This is the one.
Wilson told me no can do on a blank.
The thing I like about this one is the precise control, adjustment speed, no hex head screw to mess with and the scale actually means something. It provides the ability to dial back and forth to pre-determined settings and be right on the money or damn close. For my one PPC, I have all my touch, jam and best tune numbers recorded for a half dozen different bullets. If I decide to swap out bullets, it's a simple matter of twisting the knob to the setting I want and go.
Bob White of The Shooters Corner got me using shim sets rather than a micrometer top. Inexpensive and accurate.
I can understand your appreciation of the new Sinclair/Wilson. I see it as an improved design myself.
Seems like your smith could cut down and re-chamber pretty much any of these in smaller cartridge for larger cartridge. Open them for any larger seater stem, etc.
Not sure how much Brownells charges for just the top.
I buy Wilson stainless micro seater from Lester Bruno for $78 bucks,
He's hanging around the phone this time of year and always good to chat with although he ain't great with the computer so after our chat he hooks me up with one of the sons or daughter for my order.
Give him a call
The jlc seater is my favorite. But the hex screw on the other sinclair/wilson micrometers is only for tension. You dont have to loosen it to adjust. I like the add on top with micrometer. You can use it on multiple dies. You also gotta watch different boxes of bullets- each lot will not be the same number on the die due to lube differences while making the bullets.
same opinion for me as well
The wilson/sinclair shown above is a good copy of the jlc. I was wondering how long it would take for the copies to come out after jlc stopped making them
Larry, got a link. I'm having trouble finding it. BTW, 10% off today.
Thanks Mike. I’m going ask him about that. Love that micrometer top.
I make all of my one dies from blanks and the tops work..... if you like picking them up being so top heavy..... Jim
Jerry. I went to www.brownells.com and searched for micrometer top for wilson die. LDS
