why higher impact with lighter charge?

[BMerino]

Guys, fired my first batch of .308 handloads today and was happy but have some questions. First thing I noticed is the lighter loads of powder had higher impacts than the hotter ones. They were shot at a 100yrds. I was shooting different loads in half grain increments. I started at 42.5 gr moving up to 44 gr of Varget.

As a side note is 45-46 grs Varget sound to hot for the .308? I haven't noticed any signs of over pressure yet. Any help would be appreciated.

OCW test
Ladder test

Try these two for an explanation.

In the same weapon the faster the bullet leaves, the lower it will shoot, do to the recoil cycle, same as in pistol.

Longer barrel time, more barrel rise before bullet exits.
