I'm new to this forum and until now my largest calibre is a .375 H-H and a 45/70. By browsing this forum I became very interested in the .577 light nitro (Marrakai's stories). Some time ago there was a forum member building one on a 10g S/S shotgun but I cannot find this post back.
Would this cartridge fit in a Ruger N1 or a martini shotgun?
Best regards,
Benny
