[1] The term is an onomatopoeia of the sharp, ringing sound (or "plink") that a projectile makes when hitting a metallic target such as a tin can or a road sign plate.
[2] In contrast to shooting done at established target ranges, plinking is generally done at home in one's backyard, in an open field, or on other private land, the owner of which does not demand entrance fees.
The primary attributes of plinking that make it appealing as a sport are as follows: easy availability and a broad variety of locations, minimum cost, freedom in practice, outdoors environment, and more engaging shooting experience when compared to established target ranges.
Many shooters also find the open air to be a much more pleasant shooting environment than an indoor target range, which is usually windowless and made of concrete and steel.
Steel targets, which are used for formal action and long range shooting competitions, are also popular among plinksters due to their relative ease to set up, as well as their clear evidence of good hits.
