The RCBS Safari Die 3-Die Roll Crimp Set in .505 Gibbs is purpose-built for reloaders working with big-bore, straight-wall cartridges developed for dangerous game hunting. This 1-inch die set gives you the full tooling package needed to reload one of Africa's most respected rifle cartridges: a sizer die, expander die, and seater die with roll crimp. If you're serious about .505 Gibbs ammunition, this is the specialized setup that lets you maximize consistency and performance from one of the hardest-hitting rounds in your safe.

The three-die configuration handles each stage of the loading sequence. The sizer die handles case sizing and decapping in a single stroke—essential when working with large-diameter cases that demand precision fitting. The expander die opens the case mouth to the proper diameter for bullet seating and applies the bell flare needed for reliable feeding through magazine and chamber. The seater die completes the process by seating the bullet and applying a roll crimp, which is the preferred crimp style for dangerous game ammunition where case integrity under peak pressures matters.

Because the .505 Gibbs uses a 1-inch die body (rather than the standard 7/8-inch-14 threading), you'll need a press adapter bushing to mount this set in most reloading presses—the bushing is not included. If your press is a Rock Chucker Supreme, note that it comes standard with a 1-1/4-inch-12 to 7/8-inch-14 adapter, so compatibility depends on your specific setup. Cases must be lubricated before sizing. This is a direct-order RCBS Safari series tool for a niche but serious caliber.
