Huceco this is what I use,
This is for a 1/1/8 shot 3dram load
WST powder ( 20.0g)
waa12 red hull
the velocity of that load 1200
great for 16 all the way back to 27 yards and the perfect load of ATA meets.
hope this helps if you need any more info email me and i will try to give you my best answer.
