    Don't worry about the .454 to .452 bore issue. The bore issue really isn't a real issue.

    The real issue is cylinder throat size.

    Webley MkI thru MkIV revolvers are commonly found with .452 bores and .450 throats. Undersize throats worked OK with open base bullets, current solid base, not so much.

    Pre ww2 Colt and S&W revolvers are usually fairly close. .454 bore, .454 throats.

    However 1970s thru 1988 Colt and S&W revolvers were commonly found with cylinder throats varying betwèen .452 and .458.
