QuikLoader is a unique precision-machined 12ga sizing die. Quikloader will uniquely taper the leading 1/2˝ end of your shotgun shell to a 3° angle. #Quikloader works great for fast and efficient loading of shotgun shells into the chambers of side-by-side shotguns. The QuikLoader temporarily replaces the first crimping die on MEC Jr and MEC 9000 reloading presses to allow for easy and fast resizing and tapering your loaded cartridges.
