RCBS #48 Shell Holder 338 Lapua Magnum

If your shell holders don't securely grip the shell and firmly fit into
the press during reloading, you're bound to have headspace and sizing
problems. RCBS shell holders are manufactured to the industry's
tightest tolerances, using only the finest steel. Clip spring holds
Shell Holder in place, yet allows rotation to any convenient angle.
Fits most popular presses.
