Btw: In the pic above, that gaping black hole is where the magazine safety (only shoots if magazine is inserted) was...I took it out.
I just shot 50 rounds out of it an hour ago. My reloads; 125 gr FMJ RN with 5.2 grs Win 231 powder. Felt like a hot load, although in my S&W 659 it feels average. My Speer reloading manual from 1981 shows this combination giving ~1100 fps...
At a WAG, I would say this was sighted in for a left handed shooter. All my shots shooting right handed were off to the left; shooting left handed, I was right on the black. I can't shoot rifles right handed any more, so I try to do
all my shooting left handed. This can stay as it is.
