Name of the shotgun and link to purchase it?

That pictured is the Mossberg 500/590-12 Gauge Pistol Grip.
I used it more for an illustration/example than anything.

I pulled the image from...here...not from a dealer site.

Here is the 500 Cruiser - 20 Gauge, 6-Shot, 18.5" Barrel, Pistol Grip Stock, Bead Sight
...from Mossberg's own site.

Wood frame & stucco. About 10-12' between houses here.
See #30 and 32. I'd go with that and bb's.

smallest BB's - #8 (birdshot)...wide spread (I use #4 myself)
the smaller the number the bigger the BB's inside.

buckshot - 00 (largest) to 04 (smallest) (20 gauge rated highest is 02...no 01 or 00)
