The screw drivers are for adjusting the sights. I had only had the Ruger out a couple times, and the Smith was at it's first shoot. I put about 350 reloads down range. The windage screw on the Ruger is ridiculously small.
One hundred were ridiculously under powdered. Ran the dowel down the barrels quite a few times to insure no squibs. Had 4.1 grains of Red Dot under a 200 gr SWC. I liked the 5.5 and 6.1 gr loads with the 200gr and 5.9 and 6.3 with the 250 gr. The 6.3 is getting pretty stout.
Both guns were shooting well. I'm sure I would carry the Ruger if I were going out in the woods for the day. I kind of regretted that the dealer only had the 4 5/8" model for my trade, I was thinking about the 7 1/2", but the more I handle the shorter one the more I like it.
