DiscMan:
Thanks for posting your results. Just to be clear, were you shooting an original .50 cal DISC in your above post ?
With respect to sabots for the .458 Bloodlines, it appears Knight offers them with a supplied red sabot...(I'm guessing made by MMP).
I know MMP makes an orange HPH sabot for .458's and I've shot the 275 Lehigh's with them and found them to accurate in my .50 Disc Elite. .. What Harvester Crush Rib did you try?
Thanks... Rob
