TybrneRyan, osteodoc08 is correct I've got a great HS6 load but it's right at max in the manual so won't quote it. It's accurate, almost 900fps, & clean burning. We know HS6 is the same powder as the discontinued WW540, I came onto 5lbs of WW540 before it was discontinued & same loads shoot the same as HS6. I called Hodgdon & spoke to one of their ballistitions & his words were "yup same stuff" good enough for me. So if you ever come across any WW540 grab it, I would.
Red Dot however runs well betweemn 5 & 6grs, shoots cleanly & really duplicates the RP & WW original loads.
I like it.
