I did a barrel stub on an H&R in 38 special for shooting 250 gr. cast Boolits, and at 40 yards you can shoot a 3 shot, 5 shot or 10 shot group and there is never any paper left between the bullet holes.
Since I have neighbors that live VERY close by, I needed something that was relatively quiet and would put both front shoulders out of commission so as to not have a deer jump a fence and possibly die right next to someone's house. Yes, all legal hunting, but just have less than 1 1/2 acres where the deer bed down on my place, so I need to anchor them down fast, without cutting loose with a high powered rifle.
So far so good! 8 years, 8 deer and 8 shots fired, and none of my nosy neighbors have any idea that any deer have been killed around the area.
