This is my first thread so please be gentle.
I understand that I am sort of asking how long is a piece of string, but..
I recently opened a tin of JSB 18s (cant remember where I bought them) and they looked like they had been dropped.
Most where deformed and it got me thinking (I just cant throw them away)
When is a pellet damaged beyond sensible use (not Olympics, but going to give me an obvious flyer or miss) is it head damage or skirt? The skirt I imagine "blows" out to the barrel diameter, so minor dings there should be ok.
