Firearms with looser chambers can result in case expansion when a round is fired, leading to bulged cases that may cause jams when firing. For shooters, reliability is key – especially during competition – and unreliable ammunition is a serious issue. The GMB Case Roller HD is a machine that restores proper case diameter by removing the bulge from cases, while also resizing the rim of the case for optimal performance. The process is called roll sizing or roll-sizing, and shooters and reloaders refer to the machines as a case roller, roll sizer, or rollsizer. Additionally, the machine is designed to consistently resize the cases with less stress on the brass, promoting longer case life and improved accuracy. Designed and built with reliability in mind, the high-grade GMB Case Roller HD is the perfect solution for shooters who demand optimal performance from their reloaded ammunition.

This high-grade device was designed and built to be used in commercial applications. GMB Case Roller HD is the most advanced solution in our case rollers family. In addition to all common features for every roller version, the machine can resize both rimless and rimmed cases and has built-in additional bearings.

It will accommodate common cases from 9mm up to .300 WSM (with the support installed). It is possible to size bigger cases with the top support removed.

We have also received feedback from shooters and reloaders who have automated reloading presses that, after roll-sizing, their presses run smoother.

Notes :

Remember to order THIS part, as the machine won't work without it.

If, for some reason, you don't want to roll-size the rim of the case, you can disable the funcionality by mounting GMB shims for Ultimate / HD.

The case roller formats only bottom part of the case. So it is still required to use sizing die to format rest of the case during reloading process.

Due to some problems with the availability of components, the case roller you receive may slightly differ from the one shown in the pictures (e.g., different motor and/or gearbox brand/color).

This section view shows how the GMB case roller Ultimate and HD roll-size rimmed cases, including the rim. It also shows why the C-shaped wall is caliber-specific.
