ROLLSIZER

Rollsizing is about making reliable ammunition. You spend a lot of time, money and effort in your sport. The cost of a single jam can wreck a days shooting. Whether just plinking or at the Nationals. Having factory grade ammunition improves accuracy and confidence in your gear. Rollsizers are an investment to match your effort, they are not a gimick.

A rollsizer removes the infamous “Glock Bulge” from your cases that comes from loose and unsupported chambers and allows the cases to be resized to correct SAAMI specifications with reliable case gauging and improved feeding and more consistent ammunition performance. This is a must for competitive shooters and commercial reloaders alike.

Calibre options include 32S&W, 380ACP, 9mm, 38S/SC, 357SG/40CAl, 45ACP, 38SP/357mag, 44Mag, 308 and 223/5.56 rifle calibres. Processing speeds up to 6,100 cases per hour for pistol calibres and 4,000 cases per hour for rifle calibres. The rollsizer can easily be slowed down to suit your casefeeder by removing bolts in the conversion discs.

As of late June 2020 Rollsizer.com will be shipping most USA orders from our fulfillment center in Houston, Texas (subject to stock). We expect that stock items in Houston will ship the next business day.

Not only did it resolve my spilt powder issues it was much more precise when setting the case flare. The Dillon is all or nothing whereas Kevin’s one is a gradual expander +1 from me
