LAST EDITED ON May-22-15 AT 02:17PM (MST)[p]I love BH 209 in my Omega. I really hope your Omega likes conicals better than mine did. I would definitely start with the Hornady FPB. Get a pack of 300s and 350s. If the 300s shoot, they would be great for deer. However, the 350s fly pretty flat too, so if they are more accurate, go with them. My gun likes the 350s better for some reason.
My elk load was 95 gr of BH 209 and the 350 FPB, so I would start around 90 gr and jump by 5 gr increments up to about 110 gr. I think you stand a better chance at decent accuracy with lower loads too.
If they won't fly, you can get a barnes conical. It is called the Thor.
https://www.thorbullets.com/ and they are a solid copper bullet made by barnes.
Call him and he will send out a "sizing pack" free to see what size your barrel is.
The only 3 bullets that would fly half way decent out of my Omega were powerbelts, FPBs and Thors. Anything with a rear bell seemed to stabilize decently. However, someone else said they got some flat based conicals to fly decent by putting a MMP ballistic sub bridge. They are cheap so it might be worth a try.

I finally gave up on my Omega as a Colorado gun and got me a knight and then a White to shoot conicals with. Hope you fair better.
