So, I ran 135 atips last year in my 6.5 Creed, and am running 135 Bergers right now in my 25 Creed. There's not a ton of difference between the two honestly, which I knew before I jumped into the .25. I don't have very many rounds down range in the 25, but it is impressing me thus far. The thing the .25 Creed is giving me, which is exactly what I was hoping for, is easy performance. I'm running at 40.9 grains of H4350, running a 4 SD, and getting 2,800 FPS. I can easily push on it and get to 2,900 fps, but there isn't really a reason to do so. To get the same performance, I was close to 43 grains of H4350 in my 6.5.
So, with a stroke of my press handle, I get a bump in BC, velocity, and cost/performance; what's not to love? Is it significant? No. But, I think that argument can be made across the board when talking bullets and cartridges. Is performance really that different between a 6 BR/BRA/Dasher? Same argument. The 25 Creed, for now anyhow, maxes out performance in the Creedmoor case. It would do the same thing in the X47 case. Same thing in the .308 case. Ballistically, you're running side by side with a 6.5 PRC.
I'm going to be running it (25 Creed) in the majority of matches I shoot this year, which won't be a ton, but I'll have a better idea of performance after this year is over. As of right now, I'm very impressed with it. Who knows where I'll be with it by the end of this year. I had a simple goal for the build; a lightweight build that maximized my rifle performance in the tricky winds found out west. Would it be worth it if you were shooting PRS matches? IMO, no. When you can throw a digger and get a wind call, there's really no reason to run anything more than a Dasher or similar. I'm trying to maximize my first round impact performance and the numbers on paper show that the 25 might get me some edge hits that would be misses with other cartridges.
