I'm using mine on a 7 mag, plus 300 blk bolt action (unbelievable how quiet that gun is). 308, 6.5 CM, 223.
I have 3 Silencerco cans. Saker (Chimera now) Omega and the Hybrid 45. I put the Hybrid on my 7 mag today and it sounded like the others.
If I had it to do all over again, I might buy the Hybrid 45 first. It's a bit long, but you can put an Omega 30 cal endcap on it if you want. I don't see the need but you can.
Second choice, if the Hybrid is out would definitely be the Omega.
There is something about the tone of that can that makes it seem quieter! I believe it's the best selling can? Or was?
You can't go wrong with the Omega.
