I'm thinking that would be stretching it for night time hunting, which may be 50-75yds while using a call. I've never used night vision scope, so I don't know how effective they'd be, or better to use a red scope spotlight which is also legal here. I have a night vision monocular that you can barely see maybe 25yds and is very hard to make stuff out. Its one of the cheap Russian deals.
I wasn't sure about the power as we have them up to 40-50lbs around here, and most guys are using 243's during the day. I think some use them at night too, but that is illegal.
