My 12 ga remington 870 marine magnum, with a case or two of rifled slugs would seem to be the way to go.
If it will kill a bear, it should kill an extraterrestrial.
from #55 above:
There are multiple stories repeated over many years of the following sorts of things with guns:
1. guns just wouldn’t fire; wouldn’t work—regardless of simiplicty of the gun.
2. guns have fired and bullets have been seen to leave the gun in very slow motion and then in a short trajectory fall to the ground a few feet ahead of the gun.
3. guns have fired and bullets have been seen leave the gun in slow motion or unseen at normal speed only to hit some force field between the guns and the ET’s and then fall to the ground.
4. similarly, bullets have been seen to bounce off a forcefield shield around the ET’s and/or their craft with not the slightest effect on the ET’s or craft.
5. Guns have become hot—too hot to hold.
from #59 above:
IIRC, such things have occasionally worked—very rarely.
But the human had to swing the club etc. before the ET was aware of what was about to happen.
There have been tales where the human was picking up a club, knife or whatever and then in the midst of doing so just “forgot” what he was doing and left the club alone in a kind of zoned out state.
