20 Gauge Ammunition

The 20 gauge shotgun is a smaller caliber than the more popular 12 gauge, but it is still used for practice in some beginners. Some prefer the 20-guage for hunting particularly when targeting game birds because it is less damaging to the meat. The 20 gauge is unique in that it is the only shell with a mandated yellow color. This was determined as a safeguard to prevent gun owners from confusing the 12 and 20 gauge shells.
