#1 Snakes cannot shut off the venom glands, therefore there are no "dry" bites all have some venom to them if the fangs are in play. The real thing that happens is the snake pulls back before the pressure is applied to the glands, that is what is considered a "dry" bite, even though any venom around the fang or within the tube/groove will be deposited into the victim.
#2 I understand you do not know who I am or what I did in the invert community for many years, believe me, we know what Brown Recluses are. There are facilities that have some of my specimens on display there.
You were bitten, showed no signs, so. Many people share your experience. If you were allergic you would have.
Impressive size for a FWC would like to see pics if you have them. Note that most will never see that size out of theirs, that is quite impressive.
