Hey hunting man, I couldn't find the book that came with the rifle but I didn't look real hard its in my gun stuff somewhere. I went to savagearms.com and looked at what was there. Its different than my book but.... A 250 gr pushed by the powder they show there is 400 fps faster than the same bullet pushed by pyrodex pellets. like 2330 fps vs 1945 fps I think is what it said. I had said 2700 It may have been 2400. I don't remember .... Its faster!
