Mfr. No.: PB04

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. The #749-001-313 block only has 32 holes due to the case head size.

Brownells USA QUALITY PRODUCT 06/02/2015

I first bought a few of these about ten years ago for loading PPC and 6BR ammo. These are heavy enough to not move your charged cases around when tapping a funnel or bumping it. If a bit of powder is spilled while charging or if the case holder does get bumped, you can readily see the powder granules against the contrasting white surface and know you have one or more case missing a bit of powder. Does away with the sloppy or tight fit associated with the "one-size-fits-all".

Definitely recommended

Brownells USA own blocks for all 6 calibers i reload 01/01/2013
