wonderful suggestions so far, especially when a decent zombie is so hard to find nowadays. lol
the best non paper target i ever had the pleasure to shoot (no special effects) used to be at our saskatoon muzzleloaders range,
it was a basic rusted out steel drum set at about 100 yards off. we used either 44 mag revolver sighting almost dead on, and 357 front sight slightly raised.
the drum sits nicely on the front sights.
if you hit, you can hear the bullet punch into the barrel, but it would lose energy and can't exit, but spin inside the barrel. confirmed shot.
no need to walk out and check, like with paper. terrific lazy man approach to long range shooting.
used to bring a hibachi, some decent steaks from safeway, and bbq in between the shooting, when ready, we pack the guns away, enjoy the steak with a paper cup of decent red wine (we didn't over indulge) and then go home having had a terrific afternoon.
shooting, red meat, and a shot of alcohol afterwards, and good fellowship, what more could a man ask for? (don't answer that) regards to all
that was the time (late 70's and early 80's) without range inspectors, fear of negative puble opinions, or cops hassling you.
