There was a chap in my club, sadly no longer with us who was a superb shot, who although quite a grouch, if you gave him the time he had a wealth of knowledge. When i first started shooting i asked him how i could improve my shooting,his answer was,listen lad, practice,practice practice and when you`ve done that, practice some more. He could drive me mad when he sat next to me at the range cos he would never shut up
.But i had great respect for the man and learned a lot. Still need more practice though !!
