Best way might be to use a spotter and watch for swirl, or maybe a bullseye cam. I am not sure how spotting is after 400y, but we can watch 22lr go the distance if you can pick it up early enough (125-150 is where I typically find it on its arc up) . The distortion of the light/air is not as clear as with centerfire that’s for sure. The fresh paint helps too. Sometime I can hear with my walker electronic muffs.
Wouldn’t a nightforce shv be plenty good for this? Thinking of putting on my V22 rimfire for longer range stuff
Forgive me for asking silly questions, two things.
1. How would I know I got a "Hit"? I've made hits at 200M and got a tiny "ping" on steel, at 300M I got a VERY quiet "ding". And that's with no one else firing a shot within 100M of me. I find myself shooting into the snow just so I can see a puff kick up. Sounds to me like you guys shoot well beyond 300M, I can't imagine how anyone can hear the hits. Do you guys use paper and/or paint up the targets every time?
2. Subsonic or supersonic ammo? All my guns group better with subsonic, but the bullet drop is insane. My apps shows around 2ft of extra drop at 300M sub vs. supersonic.
Thanks.
Expensive route... target flashers. Can offer the Magnetospeed target flasher if interested. They flash a really bright light and no problem to pick up a gentle hit from a rimfire on a steel gong.
"Dirt cheap" method.... find a clear patch of sand, or dusty bank. Put a target sized ring on the dirt... easy to spot hits and misses.
At 500m, I would not expect to hear any sound....
