Thank you for the information. Does your 303/270 have any magazine mods to support feeding of the rimmed cases? And is yours the .303/270 Magnum chambering? What condition is your barrel in? My barrel is a little rough but still shootable.
I will take you advice and contact Simplex about the history, too.
cheers, Bob
