The crush rib have worked fine in the Omega rifles, no good reason to use anything else. Load pressure is about perfect. Accuracy is satisfactory. Follows is a target shot by a different Omega than the one used in the OP. The X7, which is a rifle our son and i, hunted with, last hunting season. The load was 74 (weighed) grain Blackhorn, 300 grain XTP, black crush rib sabot, W209 primer.

The following photo shows the fourth, fifth, and sixth shots i made one morning, preparing the X7 for last season. These shots were made into a target pasted over the first three shots from the clean cold barrel.













Then i was able to peel the paper off the cardboard backer, and photograph the back side; one can see the holes of the first three shots, now covered by the target used for the second three shots.
