I remember years ago I when I first got my .45 Kentucky patch and ball ML, I posted a pic of the target panel after my first day shooting free hand. I was putting most of the shoots into the black 5’ circle, so I made the comment “at least they’re Pie Plate, good for hunting”. The usual keyboard experts didn't agree.
I still have that old target panel, cut to the size of the pie plate. This comparison of it to the same heart. Makes for a good visual. Easier to see that when the term ‘Pie Plate’ grouping is used, it is in fact kill shot. Especially for larger caliber bullets like a .303, .45 ball or shotgun slugs.

Back then, I posted that same target paper fixed to the side of my Doe decoy to show the relative size of the vitals on a deer and then put the decoy out at the 50 yd panel to show the actual visual distances to the target with open sights.

I can been seen, that the 'kill zone' of the vital area at 50 yds is quite large and a fairly easy to shot with even open sights.
