Videos tagged with Wildcatting

This video is the first part of a series exploring "wildcatting" for the AR-15 platform. The hosts, Brownells Gun Techs Caleb and Steve, explain that wildcat cartridges are non-commercial rounds developed by handloaders to fill specific needs. They highlight how many popular cartridges began as wildcats. The video introduces the concept of using existing AR-15 compatible case head sizes for new cartridge development, specifically focusing on a .25 GPC (General Purpose Cartridge) wildcat. This round uses a 6.8mm Remington SPC case necked down for a .257" bullet, promising improved ballistic coefficient and velocity. The demonstration involves loading Starline 6.8 SPC brass with Cutting Edge Bullets and using custom dies from Hornady. The custom AR-15 upper receiver for the .25 GPC features a barrel from Mad Dog Weapon Systems (MDWS), a company specializing in AR wildcatting.
