Bell started with a straight magazine Dutch type 6.5X53R that he much preferred to the MS and the bullets used in the 6.5X54. The 6.5 he mostly speaks of was actually one of the 1897 versions reworked in England. He later went to the MS and was not impressed due to ammunition failured both to fire and to penetrate. I have a letter that was written o nthe subject by him that I will need to dig out for you guys to read. Poor quality litho copy, but it gets the point across great.
