My recent $5 cigar box aquisition included (5) .44 WCF headstamped REM-UMC -44 WCF- with rounded nickel primer and a rather unusual (to me) hollow point bullet. Rounds seemed very light so I pulled one and it weighs 160 gr. and is .425 Dia. Rounded blunt nosed with no exposed lead with a deep cupped base. Inside of case was clean and bright and has no signs of being reloaded. (Could be from a NPE). Powder is a perforated disk type like the old Hi-Skor. (I won’t mention how much for fear of being banned from the forum!) Did Remington ever factory load a 160 gr. HP and if not, who made .425 Dia. bullets of this type for the .44 WCF?
