I have the poop on the .460 G&A from 1973, 1983, 1989 and 1994 pubs.
Includes the cartridge drawing and some handloading info.
Also have two reamer drawings, one from Clymer
and the other from Dave Manson with "GUNS & AMMO" specified as the customer for the reamer.
I'll get it up when I get done with some chores Wife has got me doing.
This stuff is right up my alley, since I am able to pontificate to no end on .458-caliber rifles, haha.
