RST makes low pressure 3/4 oz. loads for 12 ga. No detached retinas but don't get attached to what's in your wallet. Back many moons ago I reloaded 12 gauge for a 12 year-old boy and used 3/4 oz. of lead. He shot an old gas operated Beretta that I had cut the stock to fit him. He was deadly with it on doves. I shot the same load out of my 3200 at dove and it was quite pleasant to shoot at early season birds. Shot like a 28 ga., but carried like an 8 lb. 12, which it was. Gil
