RE: H&R Ultra Slug Hunter
I too have one in the 12 gauge version. I am very pleased with it.
Very accurate. Lightfields grouped the best, but it also handled other fodder very well.
I don't know what the weight is on the twenty gauge. The Twelve with that bull barrel is obviously heavy. Not a problem if you are going to sit in one place. I wouldn't want to carry it long distances though.
