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 1" thick to provide deeper holes for your cases to sit in, great for medium and long length cartridges. The #749-001-844 block only has 32 holes due to the case head size.

Brownells USA Excellent loading blocks 14/09/2013

These are the best loading blocks out there. Cases are held snugly and they are durable, light and easy to handle. I love the chamfered mouths making it easy to insert the cases. I highly recommend them.

Brownells USA Excellent 09/08/2013

Excellent loading block, well laid out. Will last several lifetimes, my grandson will probably get it. Nice snug fit around cases but easy to insert due to a nice chamfer around the drilled holes.
