probaby the same in all makes
I gave up using aa when I ended up throwing away about two thirds of most individual tins I bought , I had sooo many which could only be described as "not quite all there",
The easiest way I found was to use intershoot , find a batch that worked and buy the lot,
Loads of people now swear by aa, so it all goes round , without being a total pellet bore if you aint done indoor batch testing you are missing something (no pun intended )
then when you think youve got the holy grail then check them in the wind , thankfully mine were ok indoors and outdoors , dont forget wash bake and various lubes, weighing them ................
sorry now boring you all , I, m off to bed )
