The Ballistic Products Gas Seal or BPGS helps the powder achieve a complete, cyclic burn, with the net result of consistently higher velocities and fewer unburned grains of powder.

BPGS wads are stackable, versatile enough to use in almost any type of hull and will load a huge assortment of recipes.

Cork wads protect the base of a shotcup in a magnum load. Different shot sizes vary the height of the load, so cork wads are placed beneath the shot. This reduces setback damage and brings the load up to perfect crimping height. These wads are light, dense, flexible and can be stacked to make your crimp just right.

Remington’s 870 Express Deer pump-action is available in every gauge except the 10. Its barrel is rifled so it can shoot slugs and sabots accurately to 100 yards – or even farther, with a properly-mounted scope, plenty of practice, and the right combination of primer and other components.

Heavy loads tend to diminish the effectiveness of the cushion. Heavier loads of shot and heavier loads of powder, compress the wad much more significantly than lighter field and target loads. Thus, the energy wave from the powder’s explosion is transferred more directly and harshly to the pellets. Probably, these heavy loads need additional cushioning in the way of felt spacers and special cushion wads that must be placed immediately below the charge of shot.
