Spider web in case
Dad and myself were reloading some 243 ammo tonight and he could not fill one case, the powder kept over flowing and when he tried to dump the powder out alot of it would stick inside, when I looked inside the case I could see some powder suspended right in the middle of the case and upon closer examination it looked like the powder was stuck in a spider web. Sure enough when I poked it out with a pick it was a silky white spider web. In over 20 years of reloading I have never seen this before. The cases were cleaned and sized and primed less than a month ago. Very strange.
