Have been impressed with Interlocks (of whatever caliber and weight) for a long time, because they especially turn into "premiums" at around 2700-2800 fps. Have seen it both with the 250 in the .338 Winchester Magnum, and the 225 at .338-06 velocities.
Great, Thanks for that, that PH squinted into the sun and said, the Three Three Eight hurts em.
