My Single-Six is a very good shooter too. This was a few years ago (my eyes are older now), 25 yards, standing, modified Weaver, with some Federal bulk,
Well, the "eyes thing" get's all of us in time.
I have a 70's 6.5" Stainless SS convertible, and a Super Wrangler I picked up out of curiosity. My 73 year old eyes are what they are, but shooting from a bench bag with .22LR or .22 WMR, they are pretty much the same out to 50yds.
I swapped out the trigger springs on both, makes it a bit easier, but so far I'm impressed with the SW.
