which one do you guys prefer for Lapua 223 brass

 

[qldreloader]

I don't bother with Lapua brass. For other brass I like the Sinclair non-adjustable one.

 

[Fuj]

I've used the Holland's for some time.

21st Innovation… adjustable and supplied with tooling for both small and large pockets…

 

[SeabeeKen]

I use and like the K&M

 

[Chiquita]

I have one from 21st and one from Hornady. Both ar6e adjustable and work the same.

IMO, all of the ones mentioned work very well.

PMA for years. Keep waiting for it to dull up!

Like @qldreloader I use the Sinclair sold carbide uniformer. Never goes out of adjustment, lasts forever. But I have found on Lapua brass it doesn't cut anything. The pockets are deep and square.

Have you ever measured Lapua primer pockets?

Sinclair Tool - but I am not sure it is necessary for my shooting purposes. However, I continue to do it nevertheless even though I have seen no difference in performance before I uniformed compared to the last several years that I have.

I like the 21st century pp uniformer, I use it to initially set the depth and then to clean pp after each firing, it works great

Is the PMA pp uniformer adjustable and is that a set screw on the side of the housing ?

Thank you guys for the replies

The K&M version has been my go-to, but Lapua or Normal in my experience don't need it, but most do.

I got and like my 21st Century adjustable uniformer, mainly because it's slightly smaller in diameter than others making is good for those pockets that are tight (smaller in diameter). Otherwise, I use an RCBS uniformer.

Only with the depth gauge on Mitutoyo calipers. I don't have any other way of doing it.

I use the sinclair tool, and it does cut on my 223 brass. Like mentioned, I use it every loading to clean the pocket also, and on some it will touch the bottom. so the bottom of the pocket is flowing. I have the accuracy one tool to measure PP depth, but i do not have any lapua brass right now that has not had the sinclair tool in it to measure.

Whitetail for 24 years. Lapua 220 Russian.

Even on the 220 Russian brass it takes awhile to see the Sinclair taking anything out of the pockets.

 

[D Coots]

I don't use it until 2-3 firings.

Interesting to note that not all brands share the same depth pockets, preset uniformer might be .122 but the pockets measure .124 or in my case .126. This is where the adjustable cutter head comes in handy.

Good point. My 6.5 PRC Peterson brass has pockets measuring .129 and the 6.5 PRC Lapua brass measures .121. For my .308 brass, the small rifle primer pockets are .119 for Lapua brass and .122 for Alpha brass. Measuring Remington 9.5's that I have, their at 1.31-1.32, which might be a problem with my PRC Lapua brass.
