Very nice roll sizer!

Frikkinitz, if you are interested in a rollsizer let me know what calibres you want and a delivery address and I can get you a delivered price. Regards Kevin

Charles. The rollsizers remove the bulge at the base of the case where the full length sizing dies do not reach. The base is sized back to a factory dimension and case gauging becomes a waste of time.

Will roll sizing tighten up a loose primer pocket?

[@rollsizer5623]

@@brianyamasaki1252 no. Nothing will fix that. Rollsizing will improve a case life and there is some evidence that the primer pocket size is retained with repeated rollsizing / reloading but it's hard to tie that back to the mg fired cases. Thebloose pockets are usually from the loose chambered /mg / blow back action guns....they trash cases badly.

this is a serious commercial grade machine at a retail price, it has the option for quick calibre conversions at a a reasonable price. one commercial operator has cycled over 1,000,000 cases through his rollsizer.com machine since late January. Enquiries via [e-mail]

I’ve just ordered up a Mark7 and roll sizing popes on my radar. where does the bulge go? Does it ultimately contribute to more case neck trimming? If a person uses a “small base die” is there any considerations to made?

[@rollsizer5623]

Also, the small base circle dies can cause a lot of problems with case shapes, notably coke bottle shapes in 9mm and others. With a rollsizer you will be able to use standard sizing dies and get a better / more consistent case shape. Small base cirle dies are not recomended with rollsizing. The key issue is to duplicate a Factory size, this will be the most consistent and reliable. Yes trimming will still be necessary but this should be minimal. We have found from feedback that case life is much better with rollsizing, any questions talk to us at [e-mail]

We have done some upgrades to the case containment spring on these machines. Stocks available in the USA. These springs hold the rifle cases better and are more stable in high processing rates. enquiries via [e-mail]

[@southernkayaker]

Yes, this machine really is. I'm still thinking this is the machine to get, just haven't committed yet. Almost there....

John Helms will let you know when I get my manual machine 😉

[@rollsizer5623]

john, any questions, please ask.

Will this uniform the rim of 223 cases as well?

[@rollsizer5623]

No. We have found that if the rim is that badly damaged it will sometimes fail under the extractor. The process and accuracy to reform the rim to a correct dimension is not economical. What we have found is the rim and case concentricity is 99.9% of the problem and the rollsizers fix that very well. It very poorly understood in general. Unfortunately normal or undersized dies cannot get the case concentric to the rim as there is too much play in the case / shellplate.

[@Trad6166]

Hmm. Now that you say it, thinking about it. I believe that is the exact problem I am running into with a pretty big batch of wolf 223 brass that I have.
