Yesterday I shot of a small sample of 21gr loads, under both 240gr FNFMJ, and 200gr plated TC.
As I am not overly accurate with this heavy revolver, I opted for resting on a bench surface to get a better aim. At 30-40ft, they were pretty close to the mark.
The 200gr were tighter, but I think that was me, more than the gun as the 240grs really do have a kick and resting on a bench seems to make that worse. I don't know what those 265gr Hornady's I have ordered are going to feel like, sat over a hot load!!
Anyway, I feel as though these loads are almost accurate as any I've had in the past. I do remember getting the holes from my factory S&B loads to touch, but there I was at 20ft, probably less.
I have noticed that all my shots are left of where I was aiming. So it could be the rearsight needs adjusting, or I've a technique issue to address. (Most likely the letter...
Being right handed that little flinch pie-chart says it might be anticipating recoil (with hot .44 loads?! Surely not!!), tightening grip, or incorrect finger position.
