Boltman, my latest high wall sporter is chambered for a 33 WCF Improved variation, made by using 338 Win Mag reamer & dies shortened by 0.400". The capacity is almost exactly identical to the 338-06, differing by only 1/2 grain, so 338-06 loading data works perfectly. A poor man's wildcat that uses readily-available reamer, dies and components. Requires annealing the 45-70 brass plus fabbing a simple forming die; I turn the case necks afterward but it's not strictly necesssary in all instances. The 338 bore IMO makes a very effective meat gun for any game in the Western hemisphere.
Regards, Joe
