I had a 61# osage self bow that I have shot for almost a year. Then I went hunting in the rain, now it is a 50# bow.  I am assuming not having any kind of weather proofing is the reason.  is this true?
			
			
			
				if you shot it wet , id say you might have caused some set...
maybe someone can give you some caul info.

				It should dry back out and unless you added set, your weight should come back up. If it is still wet clamp it down in reflex and give it a month to dry. If you haven't sealed the bow, go ahead and seal the back or it might check. Leave the rest unsealed so the moisture can escape.
			
			
			
				i thought he meant he shot it wet ,which is what i thought would make it lose teh weight. 
good luck and let us knkow what happens
