It is all there, maybe not your exact bullet, but enough to get you started. I see that seems to be where you got that data. And at 3300 fps, those max loads should be adequate and exceed veloicties attainable with other powders. Use this one for your bullet, as it is a close match. Start at the lower one and work up in your gun. So 25- 26 as you stated looks perfectly reasonable. The other one is for an all copper bullet.
