BPI GAS SEAL OBTURATOR 12ga 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.

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 .125″ 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.

Place an overshot card on top of the shot charge just before crimping. Overshot cards ensure flatter, tighter crimps; more consistent load combustion and pellet containment. Besides the benefits of a proper crimp, overshot cards do the critical work of containing pellets within the shotcup during the firing cycle and during the journey through your shotgun's barrel. Recommended for all high performance loads.
