At 1000 yds would a .338 still penetrate an engine block. 2nd question, "penetrate an engine block" means exactly what?

I think most people really mean that it cracks the block or goes through the outer cast iron casing.

It would take a really powerful one to go clean through the block!

in my book penetrating an engine block means cracking the water jacket

At 1000 yd most .338's would probably crack a small block chevy, but a big diesel block is another story, it would all depend on where you hit it
