Rollsizer

Not that one.

Roll sizing works to fix the lower case where the die can't reach. Collets for lower case also works, belted cases are that main area.

I had a previous type of roll sizer that used plates milled to the cartridge taper. Util is was stolen. :( 45ACP, 9x19, 223/5.56, 38 Super and I think I had a plate set for 30-06/308 family cases. Like this one the "shrink" was adjustable.

I don't understand "clickers" do you?

Interesting I think I personally would have to shoot way more, and hotter loads to justify it, but seems like a well built/thought out tool to extend brass life.

When I used a roll sizer it was for the ammo that went into race guns. To me that is where it shines.I don't race anymore. Wasn't very good, my friends did it, so I did it.

"F-Class John" from the video mentions "clickers". don't know what that is. If you do, please share.

As JAYgs8163 explained it.. A clicker is what happens when a piece of brass expands at the WEB from pressure, and stick, clicks,pops. The PRC case design has very tight tolerances though. So, 6.5PRC brass is spec'd at about .526-.528 when new at the web. Chamber spec is .533. Resize die spec is .532-.531. So the chamber spec is so close that when fired a few times the case hardens, the web gets stubborn to resize, and it becomes so close that when fired, it sticks and then clicks or pops at the top of the bolt stroke during extraction of the spent round.
 
I do not own one, but my club does and I have used it on my 260AI, 6.5x47 and 7-08. It does what it is designed to do, however, its benefits for me are difficult to ascertain in regard to case life or accuracy.
My 6.5x47 is a genuine .1MoA capable shooter, it had zero effect on this, it did make cases easier to chamber, as it has always been tight in the expansion area after the first firing by design.
It will make a case more consistent, so over many firings it will negate bad cases causing fliers to some extent.

Cheers.
 
not a ba person necessarily, but do shoot tons of ar's! this was mentioned (clickers) as some have issues of cartridges not chambering due to the 200 line. some try to resolve by sanding down the shellholder and i don't remember what others have tried? i must be the luckiest person in the world not to have this issue with any ba or gas gun i have so far (still have some i haven't shot yet, 6.5prc, 7saum, 7-08 in ar's), but the dies (mainly redding) have worked for me. even my glock barrels and supposed brass bulge i can still fl size and chamber my 9's, 357sig, 40s/w, 10mm and 45acp's. i run all my cartridges at near top pressures for reference. being on this forum has brought me into a rabbit hole of reloading items that might need to be bought? yet i still haven't changed my practices. looks to be a good solution for longer brass life?

i thought clickers was when extracting the extractor would jump off leaving the case in the chamber due to the 200 line bulging enough to seize from pressure? seemed to be a r700 complain or rebated rim issue?
 
I helped rebuild and then I redesigned roll sizers for some friends who were in the indoor gun range business back in the 80's and 90's.

When the early Glocks came out, it became even more important to keep the 9mm brass from creating problems, but the problem predated the Glocks.

Any time the local LEO/MIL folks used the range with some poorly chambered rigs, the brass would get mingled with everything else and that was also a problem that required a roll sizing method to iron out.

Those machines predated me and they were sold to an outfit and moved to Las Vegas when my friends sold their range.
