Win AA preasures
 

Does anyone know what kind of pressure the Winchester AA and win AA sporting clay loads in 28 gauge produce out of the box from the factory? My reloads with longshot give me about 1200fps and 9800 psi according to the hodgden charts. Just wondering how high the factory pressure might be prior to my reloading the hulls.
Thanks

Would be nice to know what the factories are pushing out of the box. I load lots of rem gun clubs and the data for my reloads are very similar to the win's listed above. But where can we get the data showing what we are buying when we buy a new box of shells???

GoooooooD Question...
