300gr. 44mag & 45colt
I have some Win. 296 & some Sierra JSP 300gr. bullets to load up in both the 44mag & 45colt. For Rugers.
I've loaded Speer & Nosler behind 21grs of 296 .& Hornady XTP's behind 19grs. In 44 mag.
And in 45colt Speer 300's behind 22grs. of 296.
But I have no data for Sierra 300gr. bullets.
