Opportunities to progress shooting abilities in the UK can be limiting
At a club level, there are often seasoned & experienced members who are willing to pass on information. This information is often tainted with personal opinion & is rarely personalised to the shooter.
At the other end of the scale there are a few top level shooters who run day seminars for groups. One aspect of this method is that the group has to go at the rate of the slowest learner, the seminar rarely focuses on what each individual student needs & can be more of a demonstration of skill from someone who may or may not be good at communicating what is required to achieve the result they are demonstrating.
