Bob Brister in "Shotgunning, The Art and the Science" strongly suggested learning two eyed shooting via the BB gun in the backyard.
I was really surprised to find that many of these shotguns have an LOP of 13 1/2 to 14". I picked one with an LOP of 12 1/2" and both my wife and I have been shooting at a swinging Coke can. I noticed that both of us showed a major improvement with practice. I'm thinking that this improvement is very positive. Now, the gun is closer to fitting Amy than myself, but that was the plan. The BB gun has made me more confident in shooting with my right eye. Also, it is great to just head out to the backyard rather than trucking down to the range. It has been fun. Never had one of these in my youth.
Just be warned that these things like to come right back at you and were hitting me at a range of about 30'+.
