As an avocation I consult to an ammo maker and was at the range doing some chronographing on their behalf when I realized I had 5 rounds of 8x57 left and my Swede Mauser 8mm. These were loaded with a 3.4CC Lee Dipper tossing 51.5 grains of IMR 4350. I tossed them across my Chrony and got this...
This is only five rounds but I have no reason to believe the previous 15 rounds were too far off considering that the bullets went where I was pointing them. So, not absolute proof as to the value of "dipping" but enough to raise an eyebrow, eh? ~Muir
