When patterning a shotgun, a sufficient percentage of pellets within a 30-inch circle at 40 yards (the standard distance for pattern testing) is typically considered to be around 70-75%.
This means that if your shotgun places about 70-75% of the total pellets fired within a 30-inch circle at 40 yards, it has a good, consistent pattern that's suitable for most hunting and shooting applications.
However, what's considered "sufficient" can vary depending on:
- Your specific application (hunting different game, sporting clays, trap, skeet, etc.)
- The choke you're using (tighter chokes should deliver higher percentages)
- Personal preference and shooting style
For hunting:
- Upland birds: 60-70% may be sufficient
- Waterfowl: 70-80% is often desired
- Turkey hunting: Many turkey hunters prefer 85-90% or higher
For competition shooting, the ideal pattern percentage will depend on the specific discipline and distance.
