Not sure about that but what I can tell you is they shot well for me in my 25CM out to 900. I struggled a bit at 1k but not to bad, just glazing the plate really. I'm at 2920 24in with a can. I was around 2870's but I think the barrel speed up
Anyone have experience running the 25 creed in a gas gun? I hav a 6.5 craddock barrel but thinking about getting a 25 creed or 7mm-08 as a secondary fun barrel and haven't found much 25 creed data in gas guns.
