RCBS Primer Strips are designed to be used with the RCBS Hand Priming Tool. This tool is a time-saver that can hold as many as 100 primers in the included primer tray. In addition to holding up to 100 primers at once the RCBS Hand Priming Tool features a RCBS patented safety mechanism that keeps the seating mechanism separate from the primer supply eliminating the possibility of tray detonation.

These blue RCBS Primer Strips are designed for use with #250 Large Rifle primers and #450 Small Rifle Primers. Make sure to choose the right size for the cartridge caliber you are reloading.
