While at Cabela's yesterday I found a box of Hornady 300gr XTP for $6 a box of 50. I only have Unique powder right now but I couldnt find load data for this powder. Im planning on getting a different brand of powder just wondering if anybody knows of a load with Unique. Or what brand of powder would work good with 44mag. These will be shot out of my S&W 629 with an 8 3/4 inch barrel. Thanks.
