Given that time line and gravity readings I would guess the bottle bombs were a result of contamination. How do you sanitize your bottles?

This is the easiest wy I have found:

dishwasher, we have a newer one that is stainless steel that has a sanitize selection on it. i use that for new bottles. for re-used bottles i use star sans or iodophor and do the submerse in the sink and then set to dry.

If the reading has stayed the same, then you know fermentation is done and it is safe to bottle.

There is no harm in letting it sit in the carboy/bucket for a few weeks, to let the yeast complete their work. In fact, the yeast will clean up after themselves, which is a good thing, if you give them a chance. In the future, there is no need to transfer to a secondary for this beer and many brewers would tell you that leaving it on the yeast is advantageous.
^^THIS!

I've never understood where the idea comes from to transfer out of the primary after "X" number of days. If the beer is transferred before fermentation is complete, you're removing the yeast before it's done working. Even if the beer is transferred immediately after fermentation, the yeast isn't done cleaning up byproducts that are produced during fermentation.

It's a good idea to use starsan or idophor on all of your bottles just to be safe. Actually, you ought to use it on everything that touches the wort after the boil.

The mash profile explains the 1.020 final gravity, but I'm still stumped on the bottle bombs. I used the dish washer method for years with no issues. The only time I have had gushers is from not mixing the priming sugar well.

The real formula is (OG - FG) x 131, otherwise you will end up with negative gravity.

-a.
