43Spanish RB

[mherth]

My rolling block was handed down to me and looks like a military rifle cut down to sporting size and mounted with Lyman receiver sight. Included were 43 Spanish RCBS dies and 60 reloaded rounds of 43 Mauser cartridges. Are these safe to shoot, smokeless loads per Lyman reloading book?. Don’t know anything about 43 Spanish. Bore is excellent.
