Reloading questions for 0.50 Rimfire Remington Rolling Block Carbine

[Patrick Chadwick]

- or, just possibly, a 54 Ballard (Old Rifle or Carbine) !!! (see P.138 of the book)
- or, just possibly, a 56-52 Spencer!!!
- or even a 56-56 Spencer!!!


All these are so close together, and the known specimens in the book show such variations, that some dimensions overlap and very precise measurement of the chamber cast is required.

In particular, please measure the HEAD diameter from your chamber cast. This is a vital dimension for narrowing the range of candidates for the original chambering, AND for selecting a donor case type.
