Description:

Durable and Efficient Loading Solution for Reloaders

The HEAVY DUTY POLY LOADING BLOCKS by SINCLAIR INTERNATIONAL are designed to provide reloaders with a reliable and long-lasting tool for their reloading needs.

Product Features:

  • Machined from solid white polyethylene for durability.
  • Easy to clean and dishwasher safe.
  • Custom machined to fit specific cases, ensuring a snug fit.
  • Finger grooves on the sides for a secure grip.
  • Slight chamfer on each hole for easy case head entry.
  • 50 round blocks are 1" thick, ideal for medium and long length cartridges.
  • Model #749-001-844 features 32 holes due to case head size.

We use white polyethylene because it allows for easy visibility of spilled powder, making cleanup a breeze. With these loading blocks, you can reload efficiently and effectively.



Top takeaways

  1. The blocks are machined from solid white polyethylene, making them durable and easy to clean, with dishwasher safe compatibility.
  2. Designed with finger grooves for a secure grip, each hole is chamfered for easy case head entry, enhancing the reloading process.
  3. These loading blocks accommodate 50 rounds, except for the #749-001-844 model which holds 32 due to case head size, and are suitable for medium and long length cartridges like 223 and 243 WSSM.

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.
