Yep! For home, this is my choice...
20 gauge and #4 buckshot.
Still shoots 00 buck, easier on the body to shoot and shorter than a full butt stock for handling in close quarters.
No Man's Land 20 gauge #4 buckshot impacting 20% ballistic gelatin HIGH RESOLUTION
Another thing is varying rounds.
5 shots (without one in chamber)...bird shot, bird shot, buckshot, buckshot, slug.
You can vary the loading pattern as you choose and fire as the threat applies.
Just some other things to consider.
I dunno, I prefer kill rounds and as many as I can load and have available.
I used to have a Mossy and a Stoeger P-350, both with 18" barrels before I lost them in that tragic Lake Mead boating incident.
Before that, I was thinking about a pistol grip for at least one of them.
Looks a lot like a Mossberg 500 a very good friend of mine has, 12 ga, 20 inch barrel, but with a sling that comes across the belly and around the elbow of the triggering arm to help control and absorb the recoil. Works well with 00 buck and slugs. His preference is to alternate the two. I have fired it numerous times. A perp coming through the front door doesn’t have a chance.
Eighteen years ago I spent a weekend dove hunting with a borrowed 12 ga. I had a very painful shoulder after that weekend. But we went through several boxes of shells. It was definitely an over-dose of 12 ga. Mind you that was my first experience hunting, and before that I had never fired a 12 ga.
