I don't think what you're describing will help you at all in terms of wingshooting. The only in-house training I know of that you can do with a shotgun is simply mounting the gun repeatedly; swinging and pulling the trigger for a light adds nothing. Do the mount in front of a mirror with the intention of pointing the gun at the reflection of your eye in the mirror. NOW you can accurately gauge whether you are looking exactly down the rib, and that the barrel is pointed dead on to where you're looking. This will 'burn' the proper mount and sight picture into your arms, shoulder, and cheek, so that when you go to the trap/skeet range you only have to focus on swing and lead. You MUST shoot to learn wingshooting, no way around it. And if you have experienced skeet shooters with you (I mean REALLY experienced guys) they can really help you sort out the problems - head off stock, stopping gun, no swing, behind, above, feet wrong, etc.
