well, i'm going to have to partially take back what i wrote. after a quick search here, seems there are plenty of people who have successfully primed to 3 vols in standard bottles. there were some stories of bombs, but far fewer than the success stories. there are some smart sounding people (like him saying keep it under 3 but seems like going to 3 is a safe bet.
personally, i have enough thick glass bottles stored up that when i want to go to 3 vols or over, i can do so without needing to use regular ("thin"?) glass.

interesting, didn't know that.
to check this out i weighed a bunch of bottles. here are their weights, in grams. name of brewery included when known/identifiable. these are single data points, i wouldn't extrapolate too much.
198 (New Belgium)
192 (Kalibur non-alc)
176 (short like Sierra, thin collar)
195 (short like Sierra, thicker collar)
(average: 210.4 with the Duvel; 203.5 without it - i.e. "regular" 12 oz bottles)
