I have an 8 shot 100 yard group that went into about 1 inch today when I was chronying some loads,not quite as tight as this three shot group but will post in a bit.The military guys at the range had three nice shotguns,one mossberg had a 14 inch barrel that apparently is not restricted.Those guys must have shot 150 rounds through them in about half an hour.Nice guns.I let them shoot my garand a bit.Nice people.Part of the fun of goint to the range is the nice people you meet.Spruce grove range has some very nice members.
