:grin: Thanks, WNY_W!
At first I thought I would be expecting the groups to be tighter, BUT you're right, they are with open sights. Also, with 4 nearly identical 3 shot groups, I suppose the load has proven itself!
As to the front sight, it is now freshly exposed metal, and I intend to blue it with Birchwood Casey Perma Blue. This comes out pretty black, depending on number of applications, and works well.
