Paul,

A pistols/rifles pellet preference is always very individual, and sometimes just plain odd.

Chappies always seem to test the high-end pellets, and never think about trying the more economic end

They ought to, as they may be pleasantly surprised

I suppose very high end shooters have to guard against the possibility of the 'one-pellet-that-is dodgy' and could scupper a good score ?

Have fun

Best regards

Russ
