DMc, Since you asked...........the LR barrel for the Contender is Hollywood quiet with SV ammo and the groups above with Norma Tac and the CCI SV were shot that way with a suppressor. The Short chambered barrel is a bit louder, but I'd not say it's a LOT louder. The barrel is 20" long. When I'm disposed to heresy and shoot the CBs from the 513 with something around 24" of barrel the loudest part is the hammer strike.
Back about 10 years ago I waded into a gang of porkers and commenced to popping them. Took a sow of about 175#, then a barr of around 200#....and then 3 of the kids which were about 40# or close to it. Piglet #6 finally figured there was something in the wind and hauled butt. 5 shots, 5 dead pigs....they heard it, but couldn't quite figure out what it was, nor where to run/walk. Whole deal took about a minute, and then the work started. I never took a step after firing the first shot from behind that skinny maple tree. It made a good rest, the range was about 25 yards.
Barm, I dunno what you think will work for you or not, but my observations over the years are thus: If you start with an accurate rifle, you might, and I emphasize "might", find 100 yard precision with reduced loads in a light rifle. I doubt you'll find many such guns that tie all that together in a practical and effective package due to a number of factors. One of the first hurdles is finding something with functional terminal performance. The Hornet might do it, but you'll likely sacrifice a bit of precision with reduced loads. In my opinion, you'll likely find the light rifle you want amidst the array of single shots out there, but with a fair number of them accuracy may not meet objectives. Don't know if you'd entertain casting bullets for the project or not, but it's a pastime that might help you get there. 100 yard precision can be had with lead...my 10/22 sez so, so there. So do several other of my rifles.
Would I want to shoot small game with them? Mebbe not.
Can you slow the .44 down and hit anything? Well, out to 50 yards or so, yes.
Can the Hornet do it with reduced loads? Yes, even at 100 yards, but the referenced loads below would only be practical with head shots if you plan on anything other than scraps for dinner.
All boils down to one of those "you pay your money and take your chances" things. You can get there, but simply downloading a CF case is only one element of a larger bucket of challenge.
