Steve Redgwell (.303british.com) in New Lowell, Ont., was making a 200 gr bullet for the .303, and in different diameters, too - .311, .313 & .314, as I recall. I actually got 25 to try out in my BSA P-14 .303 Epps but so far haven't got around to it. (Time, not space, is the final frontier for me at the moment.) I don't see them currently listed on his website but it might be worth dropping him a line.
