If you have struggled to see the kill zone at either Treetops or Wendover why was this ???[/QUOTE]
I personally think the face plate colours what ever they are doesnt make a lot of difference unless you are lucky enough to be able to bracket the targets, in which case the lighter the colour the easier the bracketing should become, however the kill zones if painted black I sometimes find can be tricky to pick an aim point through the scope..ie..black mil dot against black kill zone for example? Sometimes also if using mildots it can actually blot the whole kill zone at certain distances as well.
In general I believe unless anyone can find a material that doesnt deface or loose colour with the impact of pellets there isnt much that can be done and its the luck of the draw. "keep painting people"
