    cylinder diameter question

    For a .44 special and/or a .44 mag what is the specified or design diameter of the cylinder bore which holds the cartridge? I am talking about the the hole in which the cartridge is inserted.
    thanks

    SAAMI specs say 44m .4598" just up from the rim, and .4582" at the case mouth.
    Got a .22 .30 .32 .357 .38 .40 .41 .44 .45 .480 or .500 S&W cylinder that needs throats honed? 9mm, 10mm/40S&W, 45 ACP pistol barrel that won't "plunk" your handloads? 480 Ruger or 475 Linebaugh cylinder that needs the "step" reamed to 6° 30min chamfer?
