So I pushed a slug through my 9-43 03-A3 today. The gun has always impressed me with how new it looked when I received it (in pieces) from an estate. There was no wear on the parkerizing. Anyway, the slug measured exactly .308. I could not believe it was that exact. I guess maybe this gun never saw any action after all, maybe.
I got a RCBS 308-165 SIL mold this week as well. Cast with #2 alloy and they drop at 170 grains.
