I recently received 5 .45acp cartridges which were all supposed to be Dairt brand with the sintered bronze “oilite” bullets. They all have the correct headstamp types such as RA 41 and WCC 42, however 4 of them look like typical FMJ ball loads and the bullets are definitely 230gr. One cartridge (which I suspect is the only true Oilite type) has a projectile that is about 136gr.
I see some talk of the Dairt load here:
But what was the correct grain weight? Would these other 230gr loads be confused from the Concord reloads using the similar box type?
