Sorry, between work, harvest, and an ongoing family matter, I've been spread a little thin lately. I will do some more research in the next few days, but I think I remember reading somewhere that wet phone books worked well. Of course at this point, I may just be hallucinating. I definitely want to do this test, and do it right, and good weather may be coming to an end. Did you say you had a chronograph? I was looking at them when I was shopping for re-loading equipment. That will be my next purchase.
