Sinclair Expander Die Body .17 - .338 Calibre 7/8 X 14
The Sinclair 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 Generation II dies are precision machined from stainless steel and the 7/8 inch - 14 dies include the Sinclair Stainless Steel Split Lock Ring.
All expander mandrels for Sinclair Expander Bodies are sold separately
