Rcbs 3 Die Roll Crimp Set - Legacy .45-90 2.4 Sharps Straight
$84.49
The RCBS 3 Die Roll Crimp Set for .45-90 Sharps is built for shooters who reload classic black powder cartridges on original or modern reproduction rifles. This Legacy series die set handles the specific demands of straight-wall cases like the .45-90 2.4—a cartridge steeped in American hunting and long-range rifle history. Whether you're forming match loads for a Sharps rifle or working up hunting rounds for your reproduction piece, this three-die system gives you the precision tools to do it right.
The set includes a sizer die that resizes the case and removes the spent primer (note: cases require lubrication before sizing). The expander die then opens the case mouth to the correct diameter for bullet seating and imparts the bell needed for reliable bullet feeding in straight-wall applications. Finally, the seater die seats your bullet and applies a roll crimp—a critical feature for black powder cartridges, where a secure crimp helps maintain ignition and case integrity under the pressures these historic rounds generate.
Black powder reloading is a deliberate process that rewards attention to detail, and RCBS's Legacy line respects that tradition. This die set is engineered for the shooter who understands that ammunition for a classic cartridge deserves more than generic off-the-shelf solutions.

Frequently Asked Questions
What's included in this RCBS 3 die set?
The set includes a sizer die (with de-priming), an expander die, and a seater die with roll crimp. You'll need to provide your own press, shellholder, and case lubrication.
Will these dies work with reproduction Sharps rifles?
Yes. The Legacy series is designed for both original and modern reproduction black powder rifles chambered in classic cartridges like the .45-90 Sharps.
Do I need to lube cases before using the sizer die?
Yes. Cases must be lubricated before sizing to prevent sticking and damage.
What is a roll crimp, and why does it matter for black powder loads?
A roll crimp bends the case mouth slightly inward around the bullet, securing it in place. This is particularly important for black powder cartridges, where the crimp helps maintain pressures and ignition consistency.
