Hey, you're obviously better off than most here. You want to learn some shotgun skills? Go shoot trap. I shot four rounds this morning (100 rounds give or take a couple for bad birds) with my Mossberg M590 (2.75" shells / 7.5shot) & shot a 16 average in rather high winds (one of the local highways was shut down due to wind). The state ranked shooter next to me shot a 17 or 18 average with an proper trap gun. In optimum conditions (light and wind), most anyone with reasonable hand-eye coordination should be able to pick up 2/3 of their birds.
Someone asked about my skill level. I'm not sure how to characterize it. I've never been in a firefight before, never been in the military, never been in the police. However, I enjoy going to an outdoor range and shooting at paper targets (cirlces with paint, rather than a bowling pin, which is ridiculously easy to hit when you're relaxed and taking your time) usually from a distance of 50 feet or so. I took two semester-long basic firearms courses in college, where we mostly fired pistols and rifles in .22LR at paper targets 50 feet away, but also I did take a single one-on-one day-long tactical handgun course with a fellow who used to be on a SWAT team during which I used my Ruger P97DC. The instructor of this course said that I was a "great shot", and I believe that I have pretty good hand-eye coordination because I play lots of video games.
So in terms of firearms I guess I'm probably pretty wimpy but not totally unskilled.
