Thanks for everyones replies,I have had a chat with a chap on the BDS stand at the Westcountry Game fair,and he confirmed that it is not a legal requirement to do the dsc1.But,I did agree with him and yourself Foxhunter,that it would be a good idea (safety wise and overall knowledge wise)to take the dsc1.
I suppose I was loathe to cowtow to the police and their bully boy tactics,you know.....a slow erosion of our rights,and all that.
I do however take my shooting very seriously,and will take the dsc1,probably in September at Cirencester.Thanks again all of you.
