Winchester say around 3060 fps at the muzzle, but as we both know that can vary from gun to gun. I am happy with the accuracy and the performance so far. While I have MANY guns, this is not my favorite, but I am taking a liking to it! I am not one that jumped on the short mag band wagon, I actually bought it at our NWTF banquet for $210.oo right before winchester stopped making the 70. I bought it because of the deal, but am very suprised with how well it's doing. The furthest animal I have shot with it was about 200 yards (pig). If I was headed on a monster buck hunt, I will be carrying the 7mm STW, but the 25WSSM has done really good so far!
