Looks like I've got a Ruger #1S 475 Linbaugh NIB coming my way. Zero experience with .475" bullets or undersize soft lead bullets to paper patch. I doubt many of these 475LB Rugers are 'out there' and even fewer have experimented with PP'ing the few bullets available.
What have you heard?
Thanks, and if you couldn't tell, I like 'odd ball' cartridges. Looks like maybe Ruger single shots are getting scarce, too.
