Where i shoot there are 3 of us that have permission on a 600 acre farm. 1 of us being RFD therfor there is a wide variety of firearms from Airgun, Rimfire and CentreFire (Alot of Gun Testing and Reviews done also)... one of us uses Nightvision on the farm a few nights a week and rang today questioning had us other two been out at which we replied no. He had spotted random people walking and also people with lamps etc...
Dont think people realise the hidden dangers between (Nightvision)Scopes and bright light! Blind For Life!
At 200-300 Yards with the CentreFire and Nightvision who knows
