The rollsizer removes the bulge in the base of the fired case to bring the case back into specification to allow reloading. The rollsizing process is extremely complicated but can be broken down into 3 main areas;
The base of the case is rolled back to what is used by new OEM factory ammunition
The base of the case is forced back concentric to the rim and
The base of the case is squared up so the case mouth meets the sizing / powder funnel at reloading
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. Some spares are supplied with the machine and include retention springs, activation levers and case push return springs. Refer to the rollsizer.com terms and conditions on the website,
All commercial rollsizers will be supplied with either a 110VAC or 220-240VAC single phase motor and a moulded plug to suit the country of purchase. 220VAC orders outside of Australia will be supplied with a European plug and customers can spource a Euro to USA adaptor plug or install a new plug to suit. All 220VAC motors supplied to the USA / Euope can be run on 50Hz or 60hHz.
Shipping dimensions: 470mm x 300mm x 300mm, approx 65-70lbs depending on the conversions ordered.
The rollsizer.com business started out of a genuine personal need to be able to process and reload brass quickly, reliably without problems. the initial idea started in mid to late 2014 as a need to size 357SIG cases as the standard methods did not provide reliable case formation, magazine performance or consistency in accuracy / performance on the range. The limitations of reloading presses, dies and various “bulge busting” options were looked at and none could reliably reshape the brass back to the OEM or factory case dimensions. So what did we do? We made our own machine and made lots of versions along the way with different levels of results. The rollsizer.com business formally launched in 2017 and has expanded and grown ever since with the addition of the DC and manual rollsizers. most of the original rollsizers sold in 2017 are still in use. The use of rollsizing in brass processing is now mainstream and is considered a baseline minimum process in all quality remanufactured brass and ammunition.
The Automatic decapper was launched in 2021 and despite it being designed as a domestic machine it is in use across many commercial businesses as well as competitive shooters.
Kevin is a Mechanical Engineer with over 30 years experience in design, fabrication and manufacturing. He is a Master Graded competitive shooter and regularly competes nationally and internationally including representing Australia (when we can get to matches….COVID is not helping). As an active competitor Kevin is very much aware of the importance of reliable ammunition in our competitions, a single 3 second delay due to ammunition can loose a podium slot.
Kevin is also the father of the Rollsizer.com sponsored shooter Paul Whitehead. Paul is the current Australian Standard Division Champion (2021, 2022) and is a GM graded shooter with a custom 2011 supplied by Robert Griffirth Gunsmithing in Western Australia.
Paul started competing at the age of 11, represented Australia at the age of 14 and is representing the Australian Mens team at the 2022 IPSC World shoot in Thailand in November 2022.
