I'm shooting 250 gr. yellow tip Shockwaves with the yellow sabots, 110 gr. 777 ffg, Win. 777 primer. That's what I've been using in my Omega, except with a Harvester crush rib sabot. I haven't had time to try different combinations because the season is stii open. It shoots plenty good enough to hunt with. I took a doe with the Pursuit the first day i hunted with it.
