I loaded up to 48 grains before I reached the same case expansion as remington 240 grain factory ammo. But I still think it is a slightly hot load, so I'm considering to reduce the load to 47 grain, just to be on the safe side.
Don't ask me how VV came up with those loads. Both max loads with n120 and n130 will cause the bullet tip to get flattened under loading, cause they're so compressed. So the trajectory gain in high velocity will be reduced in lower BC.
