Rcbs Full Length Die Set Group D Bottleneck Cartridges .338 Norma Mag

The RCBS Full Length Die Set for .338 Norma Mag is a bottleneck reloading die set built for precision rifle handloaders who demand repeatable, SAAMI-compliant cartridges. Whether you're setting up for long-range hunting, match competition, or developing loads for this powerful magnum, this two-die set gives you the essential tools to resize, deprime, and seat bullets consistently.

The Full-Length Sizer Die handles the critical first stage: it resizes the fired case body to SAAMI minimum dimensions, deprime the spent primer pocket, and expand the neck to accept your bullet. RCBS engineered this die with vents to prevent case damage from trapped air and excess lubricant buildup—two common headaches that can ruin brass or create inconsistent sizing. The die maintains headspace at minimum tolerances, so your case length stays true and doesn't stretch during sizing.

The included Seater Die combines two operations in one: it seats the bullet to a precise depth while a built-in roll crimper secures the bullet simultaneously. This two-stage approach eliminates the need for a separate crimping step and speeds up your loading sequence without sacrificing accuracy. For handloaders working with magnum rifle cartridges like the .338 Norma Mag, that efficiency matters when you're preparing ammunition for hunting season or a match.
