I am looking for some data for a hard cast 215grn SWC and Unique. I have Speer #14 and Alliant's web site for data but neither of those lists any data for this combo. Another question - loading for 44 mag and 357 I've noticed that IMR 4227 and H4227 are 52 and 53 on the burn rate chart ( I think ) they're right together anyway, I've also seen some data for each that was the same. Are these the same powder like H110 and W296?
