We tried the MagPro, but accuracy was all over the place. H4350 and IMR7828 shot better for us. Don't overlook Retumbo if you can get your hands on it. I haven't been able to, but there's lots of info on the Retumbo and the 140 VLD on the Long Range Hunting website, last time I looked it was 60 some pages. Lots of useless blabber with some good info thrown in.
