When you suck at shooting as much as I do, having fun and making noise is often the best thing
I haven't really defined 'disciplines' as such because I'm not that familiar with what options there are.
In the US, I mainly shot IDPA handgun and precision rifle matches. I might be mistaken but think the nearest equivalent to this is CSR in the UK for large calibre and gallery rifle for .22 ? Most precision (more tactical) matches in the US employ movememt, barricades, unkown distance, incline/decline or other unusual/unstable positions, steel targets, cold-bore, moving targets and occasionally in teams with spotters and land navigation etc. I can't say I ever won or even came close to winning anything but it is a lot of fun and often involves a weekend of shooting and a good night out. I hope to go back several times a yr to keep it up if i can afford to. I am told WMS Steel Challenge might be a good place to shoot ie not a square range. Is that right ?
One thing I def want to take up is clay pigeon shooting. I only did a little of this in the US but really enjoyed it and can only improve. I did have a look through some websites on practical shotgun (never done that) and believe i need to attend a course but I think i'd like to watch a match or two before making a decision on that. It looks a lot of fun.
