You may have looked at one of my post. I have
an Omega and tried several powder/bullet/sabot.
Combinations. The bore on my Omega is really
tight. So the combination that loads easy, shoots
great is the Hornady 300gr. XTP 45cal. in the new
.451 Harvester crushrib sabot. This really works
well for me, but I have learned that each ML has
its own set of rules as to what it will load easy,
and group well. If this is not the post you were
refering to, hope maybe it helps anyway.
