I found these 3D printed hull trimmers on Ebay and thought I'd give them a try. They have worked out amazingly well! They use standard razor blades and cut square, fast and easy. I thought about the Creative Reloading Solutions, but the custom blades and cost was holding me back. I've bought several 3D printed reloading parts and have been very impressed. I've got a 3D printed case feeder for my Hornady LNL Progressive and it was a fraction of the cost of an OEM.
