A0 for 32gr steel loads

[culot]

Ciao,

I have made and shoot some 28g steel loads using A1SP powder and i easily got 430ms and good patterns.
So now im going to try the 32gr loads with A0 , the wad i like to use is the same i use in the 28g loads
Gualandi SuperG Magnum, i like to use 4: steel maby 3:steel , if i can avoid using the thick american
Steel wads i 'll be happy but if i Want to take this load up to 500m/sec i don't now if SGM could
Take the stress of that high speed..

Regards. Peter
