Great tool for internal case optimisation - Lyman Flash Hole Uniformer 7777760

robncar1's Review of Lyman Flash Hole Uniformer 7777760
We've got this tool set for .223/5.56 cases to remove internal burrs at the primer hole. Once you have your "once-fired" cases trimmed to length, use this tool to lightly chamfer the inside of the primer hole to attempt to provide an even primer ignition; thus increasing similarity between rounds, improving accuracy. Will work for other calibers too as the length is adjustable.
