    I have loaded several bullets in the .458 SOCOM, all jacketed. I have not tried the Barnes TTSX. My favorite so far is the Hornady 325 grain FTX bullet. I had zero issues with the 405 grain Remington flat nose bullets feeding, but think the 275 to 350 grain range is in the SOCOM's wheelhouse.

    Marty (Dutch last name that I cannot spell correctly from memory, Van De Veere?) originated the .458 SOCOM. His website is still operational, but I don't know how current it is: http://www.teppojutsu.com/

    I agree that a band/crimp groove is a good idea for this cartridge to facilitate a roll crimp.

    As for magazines, I use aluminum GI mags and put a half-moon grind on the front to prevent cartridges from hanging up there. I did this without waiting for an issue as I hand cycled rounds and pushed them straight out of the magazine and it looked like a potential snag point, so I preemptively made the grind. Another reason to roll crimp; one less potential snag point with unmodified magazines.

    I'm interested to see where this ends up!

    Yes, it looks as close to what we all wanted if stuck in a blender
    I am getting solid and HP both non-lube-groove
    That will make for one big, unitary, driving band
    Really excited about both the solid and the Penta Pin HP

    I haven't shot a boolit that looks like that mp- 305S. It looks like it's center of mass is forward in the nose someplace? Short shank and long nose? I think you're estimating the weight of that boolit heavy as well. I bet it will barley make 300 as a nlg fn.

    "Mr. Glenn Larsen has come out of design retirement AGAIN to offer the Design the MP Molds C460-305S- 458 SOCOM . It is spec'ed out for around 305 grains maybe a little over as a solid and 290ish with the largest HP. Should really optimize the performance of the standard twist rate and potential of the cartridge. Pin options is where this will be a must have. Will come with Large Penta..."

    Mr. Larsen either did it right or not.
    I am putting my trust in him.

    I had an idea today about tips for a hollow point. I have never swaged anything before but would it be possible to swage a tip out of soft lead and press that into a hollow point?

    Would a Rock Chucker be strong enough to swage a piece of soft lead to the shape of a polymer tip?

    Press that into a medium to heavy weight socom boolit.
