I've got a load scribbled down in my notes "to try" in my Ruger Blackhawk which consists of:

Winchester Brass
250gr. Hornady XTP
WLP primers
13.5gr. Blue Dot
COL 1.600"

But for the life of me I can't find it in any of the books or manuals I own. Not sure where I saw it.

Can anybody verify this is safe thru print material or experience..?
