Just read Pearce's article last night. Left me wondering given the barrel "work" he had to do. I am more than content with my old Ruger Carbine 44 Mag. With some bedding wotk that I have done it is a consistent 2 1/2" gun at 100 yards with the 250 gr Partition. It is my truck gun in Idaho paired with my older yet 4 5/8" Flattop 44 Mag loaded the same.
Now that little rifle or similar in something like the 475 Linebaugh or 480 Ruger, now that would be fun.
