First let me say I am just getting into reloading. I would like to begin experimenting with loads for my Wby Mark V Apex .338-378. I would ideally like to be able to load either Hammer Hunter 282 gr or Barnes LRX 280gr. I am open to other bullets and weights but I am trying to stick with something that I don’t have to worry about structural integrity at closer ranges if opportunity presents itself. From what I have read those two seem to be the best candidates at a heavier projectile weight. As I don’t want to damage my rifle or myself, that leads me into powder selection and COL.
First, does anyone have any first hand experience using USP 869, N165, or H4831? I chose those because they are available. I looked at Barnes load data and they only had up to 250gr and Hammer didn’t have any load data on their newest load data sheet for that caliber. They just mentioned that their bullets aren’t sensitive to seating depth. I understand precision is the name of the game in reloading. That said, it sounds like it would make loading with Hammers less complicated in a way. It would seem you would just need to determine a safe powder load and COL. Am I wrong in thinking that?
Second, I see COLs all over the board. Some much lighter projectiles have a shorter COL than some of the heavier ones. I don’t quite understand how the projectile can be seated deep enough to make a lighter projectile with the same diameter protrude farther. It just seems like it’s not an Apples to apples comparison. Can someone please elaborate on what a good guide for COL should be?
Thank you!
