Just bought one of these. Going to be setting up an informal rimfire challenge(rifle) course this spring. Have been doing an informal rimfire silhouette for a few years, but, too hard/time consuming for a bunch of occasional/recreational/inexperienced shooters.
Any hints on using the timer for 22 rifles, my limited use indicates that the 22 rifle report does not always trigger the timer. Do I need to place the unit very close to the muzzle, closer to ejection port, etc.
Has anyone adjusted the sensitivity(owner manual recommends against it)
