Well, my opinion only, but...
Perfection in a firearm isn't measured by cartridge chambering alone.
So far, the .327 Federal Mag hasn't been commercially chambered in a firearm I "just can't resist".
A single action .327 was a great idea, but if I can buy the same sized/same framed gun in .45 Colt, .44 mag, .357 mag, .41 mag, and so forth, then I'd likely choose the larger chambering.
Why? Because if I'm going to carry the weight, I might as well carry the power, too. Recoil is largely a non-issue for me, and I can't remember ever being in a situation where 6 wasn't enough, and 8 might have made a difference.
The .32 H&R in a full sized Blackhawk wouldn't be attractive to me, and the .327 mag isn't, either. 48 ounces is a lot of weight for a small(er) game cartridge when there are so many .38 caliber revolvers available that are easier to carry, easier to buy ammo for, and cheaper to shoot.
The .327 in a Single Six once seemed like a great idea, but I'm not sure any more. The .32 H&R is getting more and more to where it just "seems right", and I really like mine. To be honest, I can't think of a single thing I'd hunt with a .327 that I would feel undergunned hunting with a .32 H&R.
For me, it makes a nice little package for general packing and shooting needs. When I'm in more remote country, I carry something bigger, but the little Single Six is sure easy to carry, and does the job nicely.
But I'm a practical sort of fellar, so don't pay too much attention to what I say.
