I save all my milk jugs, laundry soap bottles, etc. - anything that holds water without a deposit - fill'em and shoot'em before I burn them. My parents save theirs for me too.
Comparing and testing various loads gives a relative idea of how they will perform. I test everything from .22 LR in my pistol to .30-06, shotguns and muzzle loaders too, at various ranges, point blank to 200 yards.
Sorry, no pics.
P.S. I'd look for some state or federal land open to the public where shooting is legal (not illegal) or an abandoned gravel pit somewhere in your area. Always pick up your stuff and things that the slobs left behind so that those areas are available in the future. Also look into renting or buying a place of your own in an area where you can shoot.
