Trying to come up with a good performing general purpose bullet for loading the .458 socom...
From everything I have gathered to date the Nosler Ballistic tip 300gr seems to be one of the better performers for the money. However, currently they are only sold as Sabot Muzzle Loading bullets (no bulk boxes available).
I am currently machining parts to build a swaging press (thanks to all the folks here for that info!) and would like to order my first set of dies soon. I would like to start with trying to make a good performing .458cal 300gr jacketed (open tip) bullet, and maybe later mess around with polymer tips as well. I think the most practical material for jackets would be copper tubing if I were planning on making large lots of these (any input here would be great).
Also, would the "S" type corbin dies hold up to this task for long runs or would I be better off getting "H" type dies. I plan on making two separate interchangeable rams for the press (one for "S" type and one for "H").
Here is a photo of the type of bullet that I'm talking about...
