If I am just walking, my Hornet Handi would most likely go with me, and if I was hunting- stress hunting- my handi is more accurate and I can always control my shots. If I am seriously going out to kill something or not sure exactly what is going to happen, then a shorty levergun would get the nod, a 444 carbine most likely.
I expect once I get the loads worked out, a 300AAC will probably get the nod, at 30" long, and I will pick up a youth synthetic stock set- so about 5 pounds. A contender carbine with a "Super 16" barrel is very close also, but they are like finding hens teeth. I must say, that if the law was a little different I would put a youth stock on a Rossi Mares Leg 44 mag in a minute, I cant think of a much sweeter package than that would be.
The other piece of this is the cartridge in question, most levers are 30/30 and 20 to 22" barrels, that is considerable firepower for "a walk". One of the SB1 shortys in 44 or 357 is plenty and handier
