Here are two pics of a target with 12 Ga Federal LE #1 Buck out of a Wingmaster with an 18" Modified barrel:
Follow on 4 shots, rapid fire.
I can hit what I aim at with my 12 Ga and these rounds put quite a bit of lead where I aim. I'll stick with my 12. My wife is quite small in stature and has an 870 Express 20 youth next to her side of the bed loaded with #3 buck. It never even entered my thought process to go with a .410 as the 12 and 20 are both far more versatile and have a tremendous amount of ammunition available for whatever it is we are deciding to shoot at on any given day.
