I'm new here so forgive me if this is posted in the wrong place. Perhaps an administrator could square me away. Away, I purchased a 45-70 Sharps reproduction and decided to work up smokeless loads for the Lyman Postell #457132 535 grain bullet. I chose 5744 powder after experimenting with other powders and my chronograph. Several of my friends told me they would never use 5744 because it is "way too expensive." I wondered if that were true as I was getting superb accuracy from the rifle out to 875 yards. The chart that I hopefully attached shows the relative costs of five popular 45-70 powders and the costs of each. My research shows that 5744 is actually the cheapest powder to use and not the most expensive. I have used all five of the powders and have come to the conclusion that 5744 is the one for me.
