I thought I was good enough to have this not happen to me. That was a mistake.
The real mistake was not mixing the priming solution enough! My bottling bucket's spigot had a leak, so I skipped the bucket and just swirled the mixture into the beer.
Five weeks later, after drinking my wheat beer for a solid 2 weeks a 24oz glass bottle explodes in my closet. Since I had used the big bottles first in bottling, I cracked open the remaining 2 and sure enough! Beer gushing everywhere. The rest are in the fridge in a paper bag, but I imagine these are the under-carbed beers that I kept running into.
I know there's plenty of info on the forums already, but it always helps to have reminders: STIR YOUR PRIMING SOLUTION WELL!!!
