Howdy All, Just got back from the range and shot my CZ model 3 in 300 WSM for the first time today. I loaded 180 Grain Hornady Interlock SP BT to a average velocity of 2786 fps. 60 Grains of IMR-4350. It shot to about .75 inch with 3 rounds and about 1.05 inch with 6 rounds. I had a Standard Deviation of about 22. I have just started with the Standard Deviation calculations and do not know if that is good, bad, or average. Now I did read somewhere that trust the paper, not the numbers. Any words of wisdom out there?

Thanks,
Bill
