Hornady and Starline are about equal quality in my book, but the Starline is obviously a better value when you look at the cost. It just seems like I can never find Starline when I'm looking for it. It's always sold out in .44 mag and .45 Colt. I have enough of it to wish I had more. I managed to get a pretty good assortment of .44 mag built up and I have observed how it works enough to form my opinions. On the top would be Starline and Hornady. Winchester is pretty good. I have some marked HSM that is also working really well. I hate the Remington stuff. Not that I've had a lot of trouble with it splitting, but it is so thin, it just behaves differently during flaring and crimping operations. It just looks like it will split the very next time I shoot it.
