[QUOTE="ImBillT, post: 3083418, member: 117715"] 2850fps plus or minus a little with a 133gr in a 24-26" barrel. That would be normal pressures. If loading up to ejector marks you might bump that 50-100fps. I could imagine a fast barrel, just the right powder and really pushing brass getting up to 2950-3000. Another poster claims a friend is hitting 2950fps with a 135gr. I would expect the average shooter to be in the neighborhood of 2850fps. A 6.5CM shoots a 100gr bullet over 100fps faster than a 6mmCM. Drop 10gr of bullet weight in the 6mm and the velocity is roughly equal. If a 6.5CM runs about 2850fps with a 140, then a 25CM is going to be close to that with a 133gr bullet, probably a little faster, but not overwhelmingly. [/QUOTE]
