I'm getting 1977 fps.with W 296 and the 300 gr.XTP's,and 2166 with the 296 and a Hornady 265 gr. I've killed several hogs and deer with the 265's and they shoot great,along with the 300's. The 240's will do 2255 fps. I'm using the Sierra book,with a half a grain off max with most bullets.The 180's are real mover's also at 2500 fps + Hope this helps. Digger
