   my mk4 absolutely loves the nsa 12.5 slugs lubed with Napier at a measly 700 fps. I bought the original 12.5s from a couple years ago they shot about 1.5 inches at 42yds, not great. The newest production slugs right around a half inch at 42. And serious medicine on Chipmunks and starlings.

Nice. How much of a difference does lubing do to your groups?
