The FFF has smaller grains,you might try it if you are using an 80 to 110 gr load some have had good luk with it.
My Omega will shoot 1.5 inch groups with PB and 150 APP FF so if I was going to use them thats what I would load. I tried the HPH24 sabots with XTP and Shock Waves and they both shoot tight groups out to 200 with a 130 gr load APP FF and I like them better even though most of my deer are taken between 20 and 30 yds I do have a few places I hunt where a 150 yd shoot is likely.
