    Hell no, you load to the same velocity, then you'll be getting the same pressure as the loading manual load. I wrote an extensive reloading series on this back a few issues. You may take more or less powder to equal the same velocity and pressure, depending on your individual rifle's chamber and barrel specs. The velocity is your best guide to pressure if you don't have pressure testing equipment. Just be sure you're comparing like with like, eg same barrel length - minor chamber dimension variations don't matter.

    Just the answer I was looking for.....................there are those that will not go over book max even if their hand load is well below factory ammo velocity's and the rest of us.
    "Hunting and fishing" fucking over licenced firearms owners since ages ago.

    So if you swap out a barrel, with the same chamber specs, and need 4 more grains to acheive the same speed with all variables being equal, are you saying that chamber pressure is the same on both?

    That's what I was getting at Spanners. Physically speaking it just isn't possible.
