Challenger Ammunition uses the most modern ballistic laboratory equipment for testing shotgun shells. A universal receiver, combined with an ultra-sensitive “quartz pressure transducer” and sophisticated chronograph system are used to test pressures and velocities. All other parameters are consistently inspected to insure quality control.
High tech innovations make their sure-fire primers consistent shot after shot. Slow burning powders offer unequalled performances; very light recoil, and less shot deformation. The one piece plastic wad, whether double or single piston, ensures the shooter with more clay busting and game getting performance.
A tubular reducer increases the impact power and leaves the penetrating roundness of the shot unaltered. The extra hard high antimony lead shot offers a dramatic improvement in ballistic result, maximum penetration and denser patterns.
Another feature is the fully reloadable plastic hull; an advantage for economy minded shooter. Challengers’ modern facilities include the most up to date equipment available on the market today, thus guaranteeing strict quality control.

general reference only. It does not describe the specifications of this
particular item.
The 20-gauge follows the 12-gauge as America's second-most popular shotgun gauge. And, with modern shotshells, continues to gain ground. The 20-gauge has a bore diameter of .615-inch, with modern shells in either 2 3/4 "standard" or 3-inch "magnum" length. Most modern shotguns are chambered to handle both. Payloads vary from light-recoiling 5/8-ounce loads all the way to heavy turkey loads carrying 1 5/16 ounces of shot. Standard 2 3/4" loads for targets and upland birds are normally 7/8 or one ounce. At its very best the 20-gauge does not have the capability of a 12-gauge...but with modern shot, wad columns, and chokes it doesn't give up much, and it can be built into a much lighter shotgun developing less recoil. Virtually all manufacturers offer 20-gauge guns, and they are available in all action types and for virtually all shotgunning sports. The 20-gauge joins the 12, 28, and .410 as one of four events in skeet competition, and is becoming increasingly popular for sporting clays.
