I do use the Orange sabot in ny Omega - It is tighter than in the Remingtons but it certainly goes down. That is where you could sub the black Harvester "crush rib" might be your answer. When I first heard about putting a .458 in the .451/.452 sabot i was a bit skeptical - but there are several people doing it and doing it very well. Certainlymight be the way to gofor a second "quick" shotin the Omega in a hunting situation....
