You will never feel quite complete until you have one. So look for them. So much for keeping it simple. Sooner or later you will be looking for a side by side double. Might as well be on notice.
Some clubs only have matches for the doubles.
In the next few months we will look a bit closer at the rifles and carbines, both old and new. Will try to cover calibers, barrel lengths, choice of sights. Plan to share some information about all these things called Side Matches. Until we meet up again.
