As mentioned, the bradygames guide has all the numbers for minimum/maximum ATP/MST values if you need them (it also lists all the weapons' effective ranges as well, however it does NOT in fact list their maximum grind limits, which has lead to some issues on my knowledgeable end when it came about vocally that Pizza Box was the most efficient armor for its 99 grind limit at level 14 to wear when the Guide failed to mention that <_<). If I could get my guide, or you may be able to find some stuff about it online, there could be that... if not the latter, I can provide for the former.
If only I had the technical know-how, I would help do this for you and add all the weapons with min/max numbers and the lists for weapons and their types and all that Daggart mentioned, but alas, I wouldn't be able to until I got my guide back. :<
EDIT: Oh, and in case this wasn't mentioned before (which it probably wasn't), when you grind a weapon, you also increase its minimum ATP/MST value by 2 per grind as well, meaning that its minimum damage dealt will increase too... just thought I'd mention that (though with only a +10 grind, Goof Swatter's minimum ATP value is still only 21 <_<).
