AmmoBot Steel Case Guard
Steel cases are a bane to the reloader's existence. Not only will they scratch up your dies, most of them are Berdan primed as well. Now they're even making brass-plated steel cases, so you can't pick them out by sight. We've got you covered. This handy little device slides on your case feed drop tube and will catch steel cases of any caliber as it passes by. Just slip it off of the tube and the case comes with it. Slip it back on and you're back in business.
Does not work on the magnum rifle drop tube.
