    Looking for advice on pellet sizing. I know that batch numbers and dies are important but I'm probably not at that level of accuracy yet. What id like to know is the best way of sizing pellets. I use JSB exact 8.44g 4.52 pellets as these seem to give consistently good results with the odd flyer here and there. I'm assuming that I should try and size my pellets to 4.52 as I'm guessing this would be the average size in the tin. Should I buy 4.53 to size down to 4.52 using a 4.52 sizer or am I going about this the totally wrong way.

    If you measure them you'll see they're often way under 4.52 and the head size stated on the tins is a bit of a red herring. We've even seem same batch with the head size getting smaller on the next run and actually measure bigger.

    Sizing is a dark art, what works with one gun model may not another.

    I’ve just been through a tin of JSB Exact 4.52 (batch 42480015 6) using a Pelletgage.

    Approx. 10% were 4.50, 50% were 4.51, and 40% were 4.52.
