[unless your doing something illegal who the hell cares what the neighbors think. i had a couple move next to me from the city that complained about my shooting, i told them if they didn't want to hear country noises-- don't move to the country]
Belligerant gun owners/neighbors is one of the reasons the "anti-gunners" are so so prevalent.
FWIW, the .45 Colt rifled chamber inserts, that allow firing .22 lr's in a .45 revolver, are not what I would refer to as accurate - since they're designed so the CF owner can get live trigger time on close targets like beer cans (size).
With only one inch of rifling, and specious QC, some .22 slugs cut wads, while others keyhole - as close as 7yds (21').
