I think it had a reputation for poor accuracy. Certainly Colt's intransigence on the matter of headspace contributed to that poor accuracy. From its inception until a couple of years ago, Colt had the cartridge headspacing on its semi-rim. At least that was the theory; I've never personally seen one chambered tight enough that the semi-rim didn't slip passed its seat. After over 50 years of complaints, Colt finally changed the chamber so the cartridge now seats on the mouth. Of course a company wouldn't want to rush into something like that; it might be perceived as being flighty. 8-) JHBercovitz@lbl.gov (John Bercovitz)
