There aren't any NRL22 matches in my area, but I do shoot a few local matches each month.
One is called Extreme Silhouette. The match is shot from a bench with silhouettes at the following ranges:
Chickens - 80 yards
Pigs - 120 yards
Turkeys - 154 yards
Rams - 200 yards
Its quite a bit of fun and the wind can create some challenges at the longer ranges getting the silhouettes to fall and not just spin or rock back and forth.
Another local club shoots a different version of silhouette called modified silhouette. In this match, the chickens and turkeys are shot from a bench at 82 yards and 100 yards respectively. The rams and pigs are shot at 50 yards and 40 yards, offhand.
The offhand portion is tougher than you would think. Once the modified silhouette portion is over, we switch to a longer range match, which is almost identical to the Extreme Silhouette match I mentioned earlier that the other club shoots.
Edited to add that I'm pushing hard to get a handgun stage or two added to these matches as well...
