Not wishing to re-invent the wheel, one of the best sources of Scottish, UK and international shooting-related links you’re likely to find is on the links page at the site of the Scottish Smallbore Rifle Association.  There are links to clubs, associations, national governing bodies, international federations, Olympic and Commonwealth shooting sites as well as equipment manufacturing companies and trading organisations for all kinds of shooting-related kit. Go directly to the SSRA links page from here (opens in a new tab).

Another good source of links to shooting organisations in the UK is at www.smallborerifle.co.uk. It provides information for newcomers to the sport, lists of equipment suppliers as well as a lot of technical coaching information and practice exercises for shooters who are looking for a bit of help. The site also includes a large database of clubs, and it includes almost 700 clubs and associations.
For general interest and wide-ranging discussions on all aspects of UK and ISSF shooting, the Stirton Discussion Forum is the place to go. There’s an introductiory page for guests, and you have to register to gain access to the full forum (free and easy). It’s also a useful place to buy and sell used shooting kit.
 Please note that the SSRA site is obsolete and the link to it here may or may not work in the future, and in any case the links on the page referred to are not being maintained (AFAIK). That’s not to say that most of the information is not valid or useful.
The SSRA was subsumed into the new body Scottish Target Shooting (STS) at the beginning of 2016 and no longer exists as a separate organisation. The SSRA website was still available at time of writing but its future is uncertain as its domain registration expires on 9th February 2020 and it may well disappear then. It was actually renewed in February 2018 for two years so it looks like someone is keeping any eye on it and this valuable resource of historical data remains available for the time being at least. So far, the STS site has not continued with this links service, but please write in if you see that it has.
