Maybe, but it seems a little odd since the big thing back when Triple 7 came out was loading 3 50gr pellets for Magnum performance. Anyway I found more notes with my best load which was 110Gr of FFG under a 370 Gr Maxi-Ball.
This was for an elk hunt I did in 2006. Thinking about going again this year. I have an Omega also and may try some Thor bullets in that using BH 209 and see which gun shoots better. The MAX load for BH 209 is 120 grains. I think anyone who's used BH 209 and Triple 7 would agree BH 209 is a lot more powerful than Triple 7.
