Finally, I promised a few of you that after i received my Pro Chrono and hit the range i would provide a report on my reloads.
I use a Dillon SDB and relaod 9mm and .45LC. I only had Tulammo Magnum large pistol primers for .45lc ammo so dont ask.
I used 4 different firearms, one 9mm semi auto, two different SA revolvers, One Lever action rifle, all are listed below.
Weather today: Clear to partly cloudy, 50-58 degrees during my range time.

The 5.0gr performed best at 10yds and 50yds. More consistent and accurate than the 4.6 gr loads. I will use this load for all my Cowboy guns.
I hope this provides someone with some information that they may find useful.
Had a great day today, and did a lot of shooting, now i can have fun cleaning my brass and reloading again.
