New 21st Century Super Precision Click Head Bench Rest Priming Tool

[Petros284]

Hey all-
I just talked to John from 21st Century about something he is really excited about. We all know that his hand-held adjustable priming tool is the cats meow, he once again has raised the bar! The newest version of the 21st Century Priming Tool is now available. It is called the Super Precision Click Head Bench Rest Priming Tool. Same basic design as before, but instead of being adjustable .0025" this version is adjustable by .00125" per click! This is the first Priming tool on the market with this amount of precise adjustment. Check it out here: http://www.xxicsi.com/super-precision-click-head-br-priming-tool.html.

21st Century has a new website that is being built but is up and going during the construction stages.
while checking out this new tool check out a handful of other new items including the Barrel Vise and Bolt Maintenance Kit.

John will be out at the Berger Southwest Nationals next week with some of his new items, so if you will be there be sure to say hi to him. Unfortunately I will not be there, but will be watching from the sidelines.

See you on the line and good shooting!

Thanks Pete. Good to hear from you. Looks like an interesting tool.

I really think you mean it's the first tool somewhat nearing the precision of an indicated K&M. But it still doesn't do what the K&M does..

I have an indicated k&m and with 21st century i have the new tray fed and the old coarse adjustment one. I guess you could say i have every priming tool along with these. Ill take the 21st century anytime. Matter of fact ill trade my indicated k&m with instructions and both size primer capability for another 21st century of any style. Its seated about 100 sr primers

Sweet! This was the one thing I wanted changed on this most awesome tool. Got one on order.

 

[Dusty Stevens]

I find with the coarse adj one if it doesnt bottom out i can go 1 more click and feel it and thatll make up for variances in thickness anyway so ive never felt handicapped. But im glad john puts options out there. Im liking my new tray fed one- wish it used any other tray but itll be ok. Really wish it used the rcbs tray that comes off for storage john- hint hint

 

[Grimstod]

Good to see this. I have always thought that the old one with its .002 click increments were way to course.

I have a question about precision priming tools in general.

They are pressing the primer in and supporting the rim from inside the extractor groove.

So, the depth is the result of the height of the primer, the distance between the case head face and the bottom of the pocket (in the case of pocket cutters being used) and the distance between the case head face and the rim face opposite.

What am I missing here? It seems like the tolerances would cause variation in the primer preload - potentially worse than seating by feel.

Sounds interesting Pete. I have one from 21st Century, and it's all but retired my Sinclair tool. Very nicely done.

See you in Phoenix!

You're absolutely right.
The indicated K&M is the ONLY priming tool that accounts for all these potentials to set exact preload.
And given this, it's easy to see with the K&M -that nothing will or can do this.

 

[Dusty Stevens]

I have the k&m and cant reliably feel the primer seating which is way more important than seeing variances in primer cups

 

[mikecr]

Feel means nothing at all..
I'm sure most folks would rather every primer was set exactly the same w/resp to pockets.
INDICATED K&M

The USAMU posted an article here recently citing testing they performed: seating to a known depth versus using "feel" They concluded that seating to a set depth produced better results. But, don't take their word for it test yourself. Seat 20+ primers by feel and seat 20 primers fully and to a set depth. Shoot them over a chrono and see which has the lowest SD. 20 would be the smallest sample size to get a remotely meaningful result. I'm guessing they tested hundreds to thousands of rounds before they were sure of their conclusion.

No benchrest shooters at the USAMU, but they are some of the best shooters in the world and they DO thoroughly test ideas before putting them in practice. Of course, if testing were a requirement before posting on this forum, the threads would be a lot shorter.

All indicaters are not the same, feel is.....

 

[Dusty Stevens]

Testing with br guns capable of shooting zeroes and ones like em seated by feel. There was even a thread on benchrest.com recently about it. I tried the k&m and it fell short. Its for sale matter of fact!

All this works off an assumption that primer pockets are consistent in dimensions. Good luck with that.

This is true of feel.
The INDICATED K&M assumes nothing. All is accounted for.
Dusty, did you ever use an indicated K&M, and correctly? If not, you're merely comparing one primer feel -vs- some other.
Are you suggesting you couldn't shoot your zeros with primers seated the same?

Im saying the stacked tolerances of primer pockets and cups you cannot seat a primer by measurement as consistent as you can with a solid priming tool like the 21st century. So yes you cannot shoot zeroes with inconsistent anvil crush. Good design and well thought out tho. Solid piece that does exactly what it says. Im a k&m fan otherwise. I woulda sent you this tool tom- wish i woulda known!

I am interested in the 21st Century tray primer, but I'm a bit confused because it specified a Lee shell holder. Is there a difference between a Lee 308 shelholder and RCBS or Hornady shell holders?

Thanks,

Joe

 

[Dusty Stevens]

A lee shell holder is just a disc. It doesnt have the provision on the bottom to go into a normal press
