Made up some rounds and shot them today.
They weighed from 4.4 up to 5.4.
4.4 ejected 6' and would keep the slide open on empty. All were pleasant to shoot. Don't see a need to go below 4.4 now although I think I could easily go to 4.0.
Had some blackening of the brass about 1/8" at the mouth. Wiped right off. Don't know if that is a problem or not. Saw no signs of leading in the barrel but haven't actually cleaned it yet.
Thanks for the advise. Always a pleasure to get feedback as I have no one around that has experience reloading.
