I agree with what Bronko said. I will add to that if you use a fast inaccurate load and gut shoot something it will go just as far as the gut shot animal with a slower round. I personally get a little iffy around max loads a max load on a hot day may be too hot if you tested on a cool or cold day. That can easily happen here in Alberta with a temp range any where from -40 to90 degrees. I am not saying none of my hand loads are ever max loads but they do make me nervous at times. Hand loading is an art not what a lot of people think you just find the fastest load in the manual and slam that bullet and powder combo together and go. These are the same guys who bad mouth hand loading saying factory ammo is better.
