MGM listed in their chambering list a cartridge named the 6.5 Classic...when I inquired I was told it was based on the 30-30..but they also list a 6.5-30 and a 6.5-30 Improved..I wonder what the difference is between these cartridges?? I know J.D.Jones calls his 6.5-30 Improved, the 6.5 JDJ #2..any ideas???
