The variation in peoples allowance will be mainly down to the wind changing constantly, and also how much of the pellets travel distance was affected. I was everywhere from half to one mill dot but tried to shoot when a slight lull in the wind appeared, if it didn't die down for a few seconds then I was giving it more, like 1.5 MD on bravo target 2 to the centre of the kill
to drop it, but there wasn't much of a plate to aim at on that anyway.
I think Tench's 1 mill from opposite side is like my half, as I go from centre of kill.
I rarely give more than half from centre,.Maybe that's where I go wrong?
I dont think mag makes that much difference in HFT as most people shoot between 8 and 10 mag.
