Hello I’m a new member and new to casting and reloading in general I have a 458 SOCOM and I wanna learn as much as I can from anyone who has been there and done that with this round. Please chime in and give me maybe what the best way to go is. Thanks

That one isn't extremely easy to start out with, but doable if you pay very close attention to certain things. I put an AR-15 upper receiver together expressly for use with 500-grain cast subsonic, suppressed hunting loads, so if that is your interest I can help with the vacuum of useful load data.

You haven't mentioned the firearm type or what sort of bullet weights and velocity ranges you're interested in pursuing.

That's a little different from my pistol-length system, so I'm not sure my data will help you all that much. I had good luck with powders in the range of 2400, Longshot, and HS-6. The maximum allowable pressure of the .458 Socom is quite low and can be exceeded very easily, so proceed with caution.
