.318" vs .323"
I for one won't be messing with any more surplus 8 x 57. Last box I bought from LGS mic'd at .318...which I measured AFTER shooting 2ft groups at 100 yds. I haven't slugged either of my mauser barrels, I'm pretty certain both are closer to the .323 spec than .318!
This past weekend I was hitting 1/2 gallon milk jugs at 100 yards with factory Privi. Now I'm collecting once-fired factory brass and I'll get a set of dies when I have about 100 pcs. I don't intend to shoot more than a hundred or so of rounds per year through these rifles.
