My fathers day gift to myself was a magnetospeed porter. Yesterday I took both my 223 and my 308 to get some hard data. (I'll create a separate post for my 223)
with 46.5 grains if Winchester 748 and a 155 grain Hornady BHTHP I have an average MV of 2820 FPS with and extreme spread of 55 FPS and an standard deviation of 21 FPS. At first I wanted to do some further tweaking to get the extreme spread down some but this load puts nice concentric groups in the middle of the target. It own't win the internet commando award but a 4.5 inch 10 shot group at 300 yards is well inside the vital zone of your average sized western mule deer so I'll gladly trade the internet commando award for practical accuracy and the extra down range energy. 
So when I get to hunt outside California ( we have mandated unleaded ammo for hunting here in california so I hunt with triple shocks here) This will lay the smackdown
