We call it the 50/50/50 challenge. (For most out doors it is 45acp 50yd SF target, 50rnds, shot sloe fire within 50 minute and the challenge is to keep all shots in the black. One hand shooting. As a twist Last night I did it 50 feet, 22rimfire, 50rounds, 50 minutes. The ten ring on a 50' SF target is about the size of a Nickle. I'm pretty happy with a ~95% score.
