On a turkey gun I don't think you would have a problem with that red dot scope. I have a Cabela's multi-reticle on my turkey gun and it works just fine. You shoot with both eyes open so FOV shouldn't be a handicap. I like the adjustable dot size feature.
I also currently have a Browning Buckmark sight on my AR rilfe. This is a tiny sight, smaller I believe than the Halosight and has an nice small dot. And it appears to be holding up well. Don't know how well it would hold up to shotgun recoil but there is no limits on the package it comes in. So you might want to give that a look as its only about $50. Don't know what Bushnell's price is to you on their scope.
