Commercial Rollsizer Base Unit


Rollsizer base unit only, no calibre conversion parts included.

You need to use the automated ordering process on this website to calculate the necessary drop tubes, conversion discs and levers.

The rollsizer removes the bulge in the base of the fired case to bring the case back into SAAMI specification to allow reliable case gauging and ammunition reliability.

*Please check your motor voltage is correct before proceeding to order.



The Commercial Rollsizer is designed for those who want a genuine commercial grade machine which can process cases VERY quickly. Its not Cheap, its not Cheaply made either.

The rollsizer removes the bulge in the base of the fired case to bring the case back into specification to allow reloading. Removing the bulge brings the base of the case back into specification, when combined with the normal sizing dies the case will be meet SAAMI specifications. Calibre options include most pistol calibres as well as 308 and 223/5.56 rifle calibre and hybrid cases based on those cases. Subject to a suitable casefeeder, the processing speed on pistol cases is up to 6,400 cases per hour, rifle cases up to 4,000 cases per hour. The machine is commercial grade supplied with a 12 month replacement warranty for the major components (motor, gearbox, rolling discs and case push assembly).

The major components are conservatively sized and the working components will last many years service.

The Rollsizer is supplied with a hose and adaptor to connect to your Dillon casefeeder as standard. From January 2023 we will have adaptor clip / hose assemblies to connect to a Lyman Casefeeder with the Twist style locking adaptor. This is a separate order and cannot be exchanged with the Dillon adaptor / hose supplied as standard.

Some spares are supplied with the machine and include retention springs, activation levers and case push return springs. Refer to the terms and conditions on the website,

    This product is great!

    I had a ‘brass processing party’ with a group of my fellow USPSA team mates last weekend. We cleaned & roll-sized SO MUCH BRASS!

    Several of the folks have roll sizers, but not automated like this. They were all very impressed.

    I also want to mention the great communication between the company’s owner through the buying process and post receipt of the product.
