Many years ago before the 50 BMG shooting craze was even in this infancy, we manufactured a combination of primer pocket and flash hold tools for the 50 BMG. Since then, the popularity of the Big Fifty has grown by leaps and bounds. Our customers have been requesting that we bring these tools back and we've answered with two tools that fit the bill. The BMG Flash Hole Toll features an integral 50 caliber pilot stop and works for most BMG based cartridges. The tool has a length adjustable double-ended cutter that can be chucked in a drill for use under power.
