Exactly. Put up, or shut up. Tall tales need to be backed up. Do it in competition, and we will all be seriously impressed and sing your praises. Other than that, it's just internet BS.IF you are that good - shoot a sanctioned match, get it recorded and verified, then get on your soapbox and beat your chest to smithereans!
Otherwise, its all BS - and have I got stories to tell you of the shots I just barely missed!
