Been thinking about this for a fair while, and the best way to ensure painless death is to ensure absolute destruction of the brain.
Literally, no brain, no pain.
A bulley in the right place will do it, but mosy of the the time you'll have a minute or two of realizing what you have done and feel the life ebbing out of you. This is not for everuone, though some certain people will like this feeling.
Want a sure way? Pipe bomb. Gun powder can be bought by the pound without any sort of license or check by anyone off the street. Also, a short length of pipe and two end caps, and a Piezo electric igniter can be had for literally one dollar from any dollar store out of a barbeque lighter.
Make pipe bomb. Fashion fuse with Piezo igniter. Bury pipe bomb in a very shallow depression, enough for a bit of it to stick out. Lay down with head on pipe bomb.
Hit igniter
Instant and immediate death- head is blown apart, brain destroyed in milliseconds- no brain, no pain.
It would cost less than $40.
