    Proof that you should weight your pellets before testing your air rifle.

    Steyr Hunter - Shooting weighted 4,5mm JSB Monsters in 600mm long LW Polygon barrel.

    Installed new gen hammer and spring adjuster kit as per the LG110 FT rifles to enable external hammer spring adjustment.

    Short cylinder used from 200bar until it fell off regulator set at 110bar.

    4,5mm JSB Monsters weight distribution which was used for the test above.
    Not so good a distribution, but this batch has the best POI consistency, I have ever seen.
    A couple of 250's was shot with this batch during 2017 World Champs in Australia and 2017 Nationals in Welkom.
    If you do have this batch in your cupboard, hang on to it, or let me know if it's for sale.

    Below is a weight distribution of the JSB Exact batch that I use for LV. Thanks to Kevin du Toit for handing down his left over tins of this batch to me, which I will allow me to continue shooting with it for the next year or two.
    It has a much smaller distribution than the Monster batch above.
    The straightness of the rows they are packed in, is an indication of the time of day that I have done the weighing.

    Thank you Junior, I can only confirm your statement. Weighted pellets shoot more consistant.

    Also, change in weight = change in dimension/size.
