Vapodog,
I'm late to the party, but can share my experience. I've had a pre-64 for about 20 years now. I'm very pleased with the gun and wouldn't think of getting rid of it. I've had some trigger work done on it, and it helped (a little). The barrel was re-bedded and I've fiddled with the forend screw, too (mine shoots best with the screw pretty tight). Handloads with Varget or 4064 and Hornady 165-gr. BTSP usually give me accuracy between 1" and 1.5". Same with 150-gr and 168-gr NBT's.
I've taken deer, pigs, elk, and moose with the gun.
