I also use the bulk priming method. First I boil the sugar with a small amount of water, let it cool and pour it into the bottling bucket. After this I siphon the beer onto the sugar water. This way the sugar will be evenly mixed in the batch without any stirring.
In my opinion this is by far the easiest way to prime. I don't have to prime each bottle individually, there's the same amount of carbonation in each bottle and I don't have to think about bottle sizes at all. Adjusting the amount of carbonation in different beer styles is also very easy when you prime the whole batch at once.
Usually I use dextrose (corn sugar?) for priming, but I've also used regular table sugar and haven't had any problems. I am slightly impatient however, and I prefer to use dextrose since it ferments quicker than table sugar.
The dextrose they sell here contains approximately 10% water, so the amount of dextrose needed is a bit more than normal sugar. That isn't a
problem as long as you remember to take it into consederation.
In my opinion a good amount of priming sugar is between five and eight grams per litre of beer, depending on the style of the beer. Since I use dextrose I multiply the final amount needed with 1,1.
