If I remember correctly Webley had purchased dies from Crossman but whether that was the full die run pressed in the USA or made by another manufacturer here or in Europe?
Anyway varied from 13.7 to 14.8, some dropped through my sizer whilst others needed a shove.
I still have a full 1250 box of #2 10.5 grain dated august 2nd 1997 , the price on the box says £18.99 . Most accurate pellets I have ever used the later ones were poor compared to these .
