As competition shooters we know that a freshly cleaned barrel has a different point of impact than a barrel that has had a few rounds pass through it. The first shot fired through a clean barrel is called a "fouling shot". In matches specially in fun shoots where you have more leeway its always a good idea to fire a few rounds before you get in the heat of actual competition. I personally get around this by practicing a day before a competition and not cleaning the barrel until after the competition. Some people just don't clean their barrels at all(just the chamber)until accuracy suffers due to the leading.Any thoughts?
