BPGS Gas Seal 12ga (250/bag)
The BPGS is one of our original U.S. Patented shotshell components. The BPGS was developed to provide a unique solution to the problems posed by slow-burn rate propellants; how to efficiently seal the gases and produce consistent high-performance loads. The BPGS has now been in service for over 35 years. Its longevity is testament to its effectiveness.
Countless high performance loads and specialty ammunition manufacturers depend on the BPGS plastic gas seal. The distinctive BPGS design assists the powder to achieve a cyclic, complete burn with a net result of consistently higher velocities and fewer unburned grains of powder. BPGS gas seals are stackable and versatile enough to use in any type of hull with a huge assortment of load recipes. Most reloading books and powder company manuals list the BPGS for all kinds of different shotshell loading applications.
