I shortened a 45-70 handi to 18" and use a cast 405 grain slug over a scoop of Trailboss using the 3.1 Lee dipper.  At the barrel it is fairly quiet, at 50 yards it is fairly accurate with a tru glo red dot, at my shoulder it is light recoil.  Davidsons has Talo Trapper (18" barrel) handis in stock at this time.  I can buy one here in town for right at $270 tax included, choices are I believe 44mag, 357 mag, 45-70.  I also load trailboss with a lee dipper for my 357 mag Winchester Trapper with 16" barrel. It is quiet enough that every time I use it on the range the range master comes over to see what I am doing.  Range master says that my 357 seems to be hitting short of the berm at 100 yds and asks me to put target higher when I am shooting 25 yds.  Either one of these should terminate a racoon nicely, up on a ranch on the Mogollon rim the 45-70 is a one shot drop on feral 
( abandoned ) dogs up to Rotwieler size.  I can't remember off hand which dipper I have been using for the .357.  I have a 20" lenth of brass rod I carry in the jeep to pound bullets out with, haven't had to use it yet after about 1000 rounds between the two cat sneeze loads, but I do carry it.
