For example - one ounce of shot (for example size 6) may contain 400 pellets. Anything more than an once will contain more, say and once and a quarter of size 6 shot has 470. Those extra 70 pellets fill in the gaps left in your shot pattern making it more likely one strikes a vital spot on your quarry (more dense of a pattern as mentioned above).
A draw back to having a lot of shot is if you hit a small game animal at close range with a lot of pellets its meat will be ruined.
