OK--call me crazy. I have a couple holes in my reloading bench from changing the position of my press or powder charger. I've been known to take ammo with runnout, Mark them on one side and put them in the hole and pull them a little. Works fine. Never did an accuracy check. You won't find a "cheaper" tool than that. Punch some holes in a 4x4 --tune some ammo and go tell us if it works!!!!!!
