    After a couple of recent threads I decided to revisit the weighing of pellets.

    Currently I am using JSB Exact Express 0.51 grams (7.9 grains..?? my scales say 7.8 grains)
    Batch # 36004910 4.52mm

    So.... after some hours of weighing two tins of 500 (1000 pellets)
    I ended up with three weight variations
    • 0.50 grams - 131 pellets - 13.1%
    • 0.51 grams - 750 pellets - 75 %
    • 0.52 grams - 119 pellets - 11.9%

    I then went to the range and used these weighed pellets at
    • 30 yards - my zero
    • 55 yards

    At either distance I had no discernible POI shift with any of the three weights.

    Conclusion:
    With this batch I don't need to weigh them, use them straight from the tin.

    When I get a new batch I will probably sample two tins,
    to see if there is any large weight variation. :)

    The express i have are the same ,I got bored weighing them as they were all the same on my scales ,not as fine as your,s by the look of your findings there seem,s a bigger gap with the exact,s though .

    could of told you weighing them is not really needed.

    Sizing seems to wotk in reducing the "odd" flyer though.

    Rob, Peter uses them sized to 4.49 and at 55 yards i have seenhim produce groups or around 9mm.

    6 to 9mm, can't fault them really.
    If I'm missing targets is down to bad technique by me it seems....bugger... ;)
