Went out to the Capvern club today to shoot UT. It was a lovely sunny day great for shooting first two rounds were OK shot 19 each I think but the third round was a mare. I dusted the first five and then on the sixth thought it was a no bird turned to the guy next and shrugged my shoulders, called the bird again saw nothing repeated this once more again saw nowt! what had happened was the fosse was now into deep shade and that particular target was a 45 low right to left that never got out of the shade until it was almost out of the ground! From then on the shadows lengthened more and more until nearly all shooter were having the same problem on all targets.. the round degenerated to the point that some thought it was finished with one target to shoot. I gave up I could only see the target when it got out into the sun. What worried me was the light was not totally bad just two complete contrasts of blue sky and deep shade over the fosse. I now dread shooting in really bad light will I be able to acquire the target? My eyesight is good but I could not pick up those targets
