Sinclair Poly Load Block #5S

Sinclair Poly 50rd Load Block #5S Fits: 45ACP These 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. We use white polyethylene because spilled powder shows up easily. These 50 round blocks are 3/4″ thick to provide deeper holes for your cases to sit in, great for short to medium length cartridges.,
