are these the size of a rifle round

They are too small. the inside dimensions are 1/2 by 1 7/8. they will hold a .45 acp or smaller but not a .308 winchester. They will fit 6 small round shaped ibuprofen or 3 or 4 capsule shaped tylenol or 5 ML of liquid benadryl but that is about it.

I want to use these to test aquarium water. Can they be washed and reused?

I am not 100% sure as they are not glass. I assume that if you are using chlorine or other harsh chemicals, they may be absorbed into the material these are made from. I would suggest glass just to be on the safe side. I use these for fountain pen ink and some inks stain and even with household bleach and D**n soap any new ink I put into the washed vial has a smell of the chlorine bleach. I am not familiar with how the process for you works, but I would not myself reuse them only because of my experience. Hope this helps.
