I think it's best not to put the pellets in, as they can often lead to over or under carbonation. When I first started brewing I was also interested in these for bottling as it seemed like an easy solution to a tedious process. However, I have come to find that many of the big retailers like NB don't even offer these anymore for good reason I'm sure. If I were you I would steer clear of the pellets and just go for the tried and true method of boiling the sugar with water and adding it to the bottling bucket prior to racking your beer to the bucket, then stir gently with the auto siphon it works like a charm. I also find that the calculator above works well as each beer style requires different amounts of priming sugar to carbonate the beer and be true to the style. In other words don't just use the whole pack of sugar, use the correct required quantity which will likely leave you with some left over sugar.
