The powerful 375 Magnum Cartridges are the powerhouse behind the SierraBlaster system. Each Cartridge has an initiator so you need one Cartridge for each Blast Head per blast.
The equally powerful 375 Magnum Booster Charges are added in addition to the Cartridge for situations where more splitting power is needed.
You can only purchase Cartridges and Boosters if you are viewing the site while logged into a Certified account.
These ship exclusively by UPS. USPS does not allow 1.4s Explosives so we can not ship to a PO Box.
