RCBS 300 WEATHERBY TRIM DIE -

Doubles as a visual case gauge. Run a case into the Trim Die and if the case sticks out above the top of the die, it’s too long. File down the case until it is flush with the top of the die. Then, deburr the case mouth with a deburring tool (sold separately). Cases with an overall length of 1.700” and shorter require the use of an extended shellholder.
