It was custom made to match the throats of Gary's 25-20 reamer. Most cast bullets come .259" and modern specs call for .257".
I sized some bullets down and they work perfectly. They push through the throats with only modest effort.
Tight enough to seal the gases from overtaking the bullets and softening the lead, but small enough to load with standard dies. No more extra step of a Lyman "M" or RCBS Cast bullet expander die.

- I can see that seating bullets out. Not an option... - Huey, 2018-03-13, 18:11
