Does anybody make a sabot for .458 bullets to use in a .54? Did not see any for .458 on MMP website,just wondering if there was a manufacturer that provided such an animal.
No they do not BUT i can get a Barnes 300gr 458SOCOM bullet in a Harvester 54x45 sabot and it shoots great in my GMB54-120. Its tight but works. Other .458 bullets like the 325gr FTX are too tight. Luckily i have a Lee .454 sizing die.
