Keep in mind the velocity in the book is only a guide, and is what the company reached in their "test barrel". The differences and be considerable in your gun, depending on the size of your chambers, size of the bore of your gun, the B/C gap, how much crimp you put on the case, how deep you seat the bullet, etc. To really know your hand-loads, you need to invest in a Chronograph. Remember, all of this may not result in your desired accuracy. That's why you start maybe 10% below max and work up a few tenths at a time.
