SINCLAIR EXPANDER MANDREL - 35 thru 50 Caliber Expander Die Body

4 In Stock
SKU
sinc-749008843

Our Generation II Expander Dies completely capture the mandrel within the die so the mandrel cannot pull out. An O-ring in the die cap allows the mandrel to float a bit and find its own center within the case neck. All three Generation II dies are precision machined from stainless steel and the 7/8 inch – 14 dies include the Sinclair Stainless Steel Split Lock Ring. Large caliber expander dies accept only 35 to 50 caliber mandrels. All expander mandrels for Sinclair Expander Bodies are sold separately: Find Mandrels here.

  1. Set up your reloading bench where it (and stored components) will not be exposed to heat, sparks or flame.
  2. Establish a comfortable loading procedure and don't vary it.
  3. Keep your reloading bench, equipment and area clean and uncluttered. Label components and reloads for safe, easy identification. Never use powder from an unlabelled tin.
  4. Understand what you are doing and why it must be done in a specific way.
  5. Follow loading recommendations exactly. Don't substitute components for those listed in metallic data without reducing the load and working back up.
  6. Never substitute smokeless powder for black powder or Pyrodex because smokeless powder is much more powerful than black powder. Never mix two powders together.
  7. Wear safety glasses.
  8. Stay alert when reloading. Don't reload when distracted, disoriented or tired.
  9. Don't smoke, drink alcohol or take drugs while reloading or while in your reloading area.
