I know there are multiple posts on HBT on this subject. I know what I do goes against conventional wisdom. I brew 6 gallon batches. I have a small keezer (3.5 CF) that holds three 3 gallon kegs. I prime the batch as if I'm going to bottle the whole thing. I fill a 3 gallon keg (purge 4 times at 30 psi with CO2) and then bottle the rest. The kegs sit at least 2 weeks at room temperature, sometimes longer. I have never had a keg that is over carbonated after the first pour. Everything I've read says you should use less priming sugar when kegging, but I've never had an issue. Just thought I would share.
