Spicer, may I ask why you want a .458 SOCOM? I have never known of anyone that desired to rechamber an AR for this round. Please do not misunderstand my inquiry. There is nothing wrong in desiring this or any other cartridge in my opinion. Heck, I have an interest in 4000 fps cartridges just because they travel so quickly. But I am interested in hearing why this unusual cartridge fascinates you. Thanks.
