I also have a new Omega, it has cut not button rifleing so it may need some breaking in.Since sabots don't break them in as far as I can tell I used the old way I used to use with the Hawken rifles I built. I case you are not familer with it you take a patch and round ball load with 60 or 70 gr and rub the patch with some lube lightly and then rub polishing compound into it. or you can lap your barrel. A word of caution dont over do it 50 rounds shoud be plenty.There could be little burrs and sharp edges on the cornors of the rifleing.
