The syringes I've been using since the beginning have always had this protruding dimple to seat itself when fully depressed.
Because that takes up some volume, I've always loaded .1ml more to get the actual dosage I need.
I've never truly checked if that plunger actually equals .1ml, can anybody confirm this?
See image for reference.
.1ml might not matter to most. But I pin everyday, so that much can make a huge difference.
