I watched Big Ben on YouTube last night, well I had the time you see (sorry) ! It was all about chokes and was more or less what I have advocated to a lot of people over the last 30 years of Instructing. Briley chokes (my favourites), 3/8 and 3/8 being the ideal combination. Although 1/4 and 1/4 Briley have been my choice for a while now, using a World Cup, as and when I felt the need to tighten things up for a longish target. Finally the Bull manure put about by a lot of top shooters, about the merits of Full and Full chokes and how it aids them to add or subtract lead. So, although we agree about a lot of things regarding gun set up, we are still worlds apart, well, ..............................about 3 classes actually !
