austrian rifles for the old 8x50R and the newer 8x56R spitzer have a .329 groove diameter but I never see the diameter of a british lee speed for the .315 india. would be possible to use a .323 barrel for the 8x50R but I don't know what they did then. the indians without a doubt copy the old lee speed in all aspects but nobody outside of india get one into the hands. that makes the story so mysterious.

there was a 8x50R lee speed(?) for sale here last weeks but I had other problems
