My omega loves pinnacle, 100 grains by weight fffg, variflame with small rifle primer and PR 300 gr. 44./50, teflon tape on the breech plug.
I also set up my cousins omega with 90 grains and 250 gr. shockwaves.
Amazing accuracy on both, clean up is a breeze.
A bone dry bore is a must !
I found a dealer in Dover,Del. {Shooters Choice } who said they stocked it.
I'm 120 + miles south and have found none locally.
Good luck,
