So I will preface this with the disclaimer that I am very green when it comes to loading shotshells. Recently I have been buying Winchester AA 7 1/2 1 1/8oz target loads, disassembling and reassembling with 7/8oz Lee slugs (open hull, dump shot, add overshot card & slug, re-crimp). At 25 yards off hand I'm getting about a 3" group out of my NEF Pardner single shot and it's running right at 1200fps. As I was sitting on the couch watching TV, I couldn't help but wonder how many Lee 225-55-rf boolits would fit in a 12 ga shell. Turns out the answer is 7 and the weight of those 7 is a couple grains over 7/8oz. I thought it would be interesting to see what type of pattern this load would yield. I thought I would run it by you folks to see if this is a terrible idea. Again my knowledge is limited and my assumption of this being a light target load with a lower weight than the previous 1 1/8oz of shot this shell used to hold is that it would be okay to shoot. Thoughts?
As a side note, I have pretty thick skin so feel free to call it like you see it haha. Below is a picture of the load in question prior to overshot card and crimp.
