43Spanish RB

[mherth]

60 rounds of Canadian Industries Limited Dominion, "Adapted to Mauser Rifles", Model 71. Apparently suitable for 43 Spanish?
Some loaded with 32 gr 4198H, some with 58.7 gr RS Pyrodex, and 20 unmarked. As a rule I don't shoot loads loaded by other folks. I'll pull the loads but just asking if these cases are in fact suitable for the 43 Spanish. They do chamber OK. I would like to shoot BP PP loads.
