The 450 N.E. sounds interesting. I am thinking about a .475 #2 Jeffery in a Ruger #1. No I don't need it but need would take the fun out of it. I have seen where these guns have been built and the user worked up loads to take advantage of the huge powder capacity of the case. I have a 1968 1st model 444 Marlin in less than perfect condition that I am building into a hunting rifle par excellence. Getting one of Treebone's Walnut stocks, Skinner express sights with Talley rings and Leupold glass. Total refinish and the internals all tuned. I put it on hold during deer season. My .460 Rowland is getting a 2 dogs front mirror sight which will complete that gun unless I decide to put some fancy wood on it. Its always something..........
