If your buddy was getting 2900 FPS with a 338 Edge and 300 trainers then he was leaning on it rather heavy. Shawn Carlock came up with the Edge, he also built my 338 Lapua. Shawn's load with a 300 SMK is 92 grains of H-1000, that is the same load that I shoot in my Lapua.
Not my buddy, but rather a guy that was invited to present out our predator club monthly meeting. Maybe the barrel was 32" long- it was freaking long! I could be misquoting him too.
What would be a reasonable velocity for a 338 Edge with a 30" barrel. I get 3000 with 26" and the 250. I figure I could get 2800 with the 300 but maybe closer to 2700. I have never fired one as I am pretty sure the 12 twist won't get the job done.

Berger data has max load at 84.5 grains @ 2600 fps using a 26" barrel. 92 grains seems like a huge jump!
