The funny thing is (well, possibly not for you) is that there is a LERA rule about not wearing camo gear, especially at Bisley I seem to recall. The original LERA Chairman (Roger Nation, splendid chap, much missed) used to remind us periodically. Peter may be right, it might have been an Enfield only day, but unless it was a comp, other rifles of all types are usually seen. Whatever, it was very rude of whoever it was to behave like that with a new member.
