I trust most normal capped bottles (12 and 22 oz) at 3 volumes of CO2. I've certainly bottled at that before and never had problems. From what I've seen, you can probably get away with up to about 3.5 vol in a normal bottle, but I personally wouldn't go above 3, since that's what my own experience says is reasonable and it provides a good safety margin in case of flaws. If you're really concerned, you could use European wheat bottles, which are delicious to obtain () and can safely hold significantly more pressure; I use them if I need to be in the 3-3.5 range, personally.
