I don’t expect to get any reply on this but will try any, if for no other reason than to document the round
This cartridge came out of a very old collection in New England. The headatamp is “W.R.A. 9M-M” but the bullet is silver color and looks like it is perhaps chromed. The primer is copper and is the only copper primer I have seen with this headstamp. I believe it must be a reload since the rim is worn.
The interesting thing about the cartridge is the note “SPc. Load for Sil.Tools”. I think this must mean special load for Silver Tools. There is a company (specialized machining) in Ohio named Silver Tools but it was not established until 1984.
Does anyone have thoughts about this round or know of a Sil. Tools???
