Sinclair Heavy Duty Poly Case Loading Block #4 50 Round 22/6 PPC, 357 Magnum Pack Size_1000/Bag 300 Winchester Short MagnumSinclair blocks are machined from solid white polyethylene providing the reloader with a very durable, easy to clean loading block. Each block is machined to fit the specific cases you reload and has finger grooves machined into the sides to provide a sure grip. Each hole has a slight chamfer for easy case head entry. The Poly blocks are dishwasher safe for easy cleaning. The white polyethylene was selected because spilled powder shows up easily.
