I've had several 1-4's over the years, but my present one's on my 16x16/6.5x57R Sauer drilling. When strictly hunting birds I take the scope off, but when hunting big game turn the scope all the way down, just in case I bump a gamebird. It's pretty easy to wingshoot a grouse with the scope on 1x--or even shoot a wunning wabbit!
