RE: speer grand slam bullets
I shot a moose two times with the 338-250 grain at 150 yards with my .338-06 and i wasn't happy with them. Both bullets broke up too fast for me on the heavy bones in the neck where it joins the body, and i never used them again.
Speer may have improved them by now,but ijust don't see the need to try them again, as NP's area muchBETTER design that have NEVER failed to work as advertised for me.
