BPI GAS SEAL OBTURATOR 20ga 250/BAG

Cork wads are placed under the shot bringing the load up to perfect crimping height. Cork wads are light, dense and very flexible – great for smaller pellet sizes. Cork wads can be stacked to accomodate any height requirements. Use 12 gauge cork wads inside 10 gauge shotcups and 20 gauge cork wads inside 12 gauge shotcups. Cork wads can be used in place of other filller wads but are not to be used directly on the powder.

The X12X is our best selling gas seal. Our lab has yet to test another gas seal that more effectively and efficiently seals propellant gases - even the slowest of slow burn powders. This gas seal is used by many high-specification cartridge manufacturers. The X12X is the primary wad in many factory specialty rounds, including law enforcement and military loads for all weather conditions. The X12X is symmetrical and this means that there is no need to orient it either up or down when loading. The X12X provides highly effective gas sealing with slow burn rate as well as fast burn rate powders. Dimensions: .727" x .272"

Nitro cards are used as a seal between the powder and the shot. They can be used in place of a plastic shotcup in fiber wad loads. Most modern load designs use nitro card (reduced diameter) wads within a shotcup for managing space. They can also be placed over the powder and underneath the wad to push up the entire shot column. We’ve even used these .070″ as overshot cards. They produce better crimps and serve as a valuable spacer. Nitro card wads are constructed of a specialized material selected to withstand the tortures of slow-burning powders and heavy payloads.
