I posted this over on the 458 socom forum, but I'm curious of y'alls responses as well.
I recently ordered an RRA midlength A4 upper, a set of Redding dies, 100 SBR brass (couldn't find starline anywhere), and 100 Barnes TTSX.
First off, I'm not new to reloading, I've been doing it for about 15 years. I load most of my pistol stuff on a dillon 650 with almost no brass prep. On the other end of the spectrum, I shoot CMP high power and am just getting started w/ F-class. I'm pretty particular about what I do. Here-in lies some of my questions.
For my match rounds, I uniform the primer pocket and flash hole, sort brass by weight, bump the shoulder back .003", chamfer the case mouths, weigh and sort the bullets, seat w/ a redding competition die and toss/pull rounds w/ excessive runout, size w/ a redding bushing die to .002" neck tension, weigh every powder charge, etc. You know the drill.
How many of you guys do some/all of this stuff for your socom rounds? Or, do you just load and let 'em fly? I plan to load these on my rockchucker, not the dillon.
Can I even use the primer pocket uniformer for a rifle case on a socom case?
From what I've read, shoulder bump is pretty important on the 458. How are you measuring this? For 223 and 308, I use a Sinclair bump guage. I can't seem to find something similar for the 458. Any suggestions?
I also noticed that the redding kit doesn't come w/ a "bell" die, can I assume this isn't an issue? I use one on my pistol rounds as I mostly shoot case bullets on those.
There's a gunshow coming up in Indy next week, so I'm hoping to go up there and pickup whatever I don't have for when my upper comes in. Any recommendations on a good primer? Also, for powders, which are good/bad selections for a midlength gas system for 300-325 grain bullets?
My use case is deer hunting (I'm in IN) and generally blasting stuff if it matters. Perhaps there's a better bullet? Or –– a cheaper one that'll get the job done?
Thanks for the reply grad. Do you have a middy or CAR gas system?
