The absence of Clays is a big problem for trap shooters. Many use it because it is so consistent, and is so clean. I use it for my 16 yard and doubles loads.
I still have 12 lbs. left, so I am good through the summer, but I have picked up some 700X which works well, but is much dirtier.
For Handicap loads, I use PB, but can't find any of it, either. I can use 700X for those loads, too.
I will probably pick up an 8 lb. jug of 700X on Wednesday, just in case (and so I can stand with the Hoarders).
