I use BH209 with Win209 primers in my Omega with no problems or hang fires. Just make sure the breech plug is drilled out to get rid of any carbon build up and that you're using a good snug fitting bullet/sabot combo. I shoot 110gr. of Bh209 with a 250gr. shockwave and a Harvester Short Black sabot. This load will shoot around an inch all day long at 100 yards if I do my part. There is no need to patch between shots when shooting BH209. I easily get 15 or more shots durring a range session with no hang fires or loss of acurracy. Just make drilling out the breech plug part of your cleaning routine.
