Where can you find reloading data for Remington componets?

Answer 1

Common sources include the loading manuals from Speer, Lyman, Hornaday

Loading manuals for companies like Speer and Hornady are only going to give you load data for THEIR bullets--not Remington bullets. I haven't checked Lyman yet but the load data published by powder manufacturers are typically going to list loads using bullets manufactured by the major bullet companies. I am looking for a source that publishes loads using Remington bullets myself. No, you can't simply substitute a load using a bullet of the same weight as the Remington bullet you want to use. Bullet composition and design impacts CUP's.
