Bottle bombs. Only if the beer was not done fermenting and your bottles are very light glass.
Using the NB calculator you may have primed to 3.2 volumes of CO2. My math could be wrong. I figured each bottle at 0.125 gallons. Did you confirm the SG of 1.008 with a couple of readings several or more days apart. Was the SG read of 1.008 temperature corrected?
Have you bottled in the heavy glass swing tops?
I usually have my beers in the fermentor for three weeks to allow them to clear. Fermentation is usually done by day 10 to 14. Two weeks is not unreasonable to bottle a wheat beer since by being a wheat beer they will be a little hazy.
Bottle conditioning time is temperature dependent. Warmer is faster. Too hot can lead to early staling in a month or three. At 21° to 23°C sample a bottle after two weeks of conditioning and two days in the frig.
