    I bought a box of Hornady A-Max bullets for my 308 Win. I took a sample size of 10 from a box of 100. The weight was taken from a Mettler AE200 scale and converted from grams to grains. Here are the weights as follows:

    154.75
    154.99
    155.23
    155.24
    155.28
    155.12
    155.01
    155.30
    155.14
    155.24

    The spread from high to low is .55 grains within this sample size. How much of a difference will this make in pressure with all other factors being equal? Is this a normal spread in weight with match bullets? Or do I have way too much free time on my hands and need to take care of some yard work? Let me know what you think.

    The small difference in weight will have little effect on target. The factor to focus on is your ogive to base differences, sort accordingly.
