I wonder why you'd wonder? Are you saying there's no reason to expect much?
No, I'm saying that its a single shot, and where it puts shots 2,3,4,5,etc. is way less important than where it puts shot # 1.
I'm not saying its useless info, just that one shouldn't obsess about it. I've got a Ruger No.3 in .45-70 (with a nice thick ventilated recoil pad on it) that I always considered a good shooter, meaning I always hit what I aimed at, and when I didn't it was clearly my fault.
Did shoot a group with it once, 50yds 3 shots 2.5x Post scope, two overlapping holes 3rd one a bit less than an inch away, and most likely my fault.
If it were a magazine fed repeater, where I might actually get a 2nd or third shot at a game animal, I'd be much more concerned with group size. With a single shot, not so much. But then, that's just me.
