Saw the Hornady 300 Amax mentioned on another thread. Is it true? I couldn't find it on their web site. I am shooting a 338 RUM - 300 SMKs @ 2700 and a bit. I plan on shooting things larger and tougher than deer at long range. The SMKs shoot super well. Will the 300gr Amax stick w/the SMK BC wise. How about penetration around 1K? Shoulder or boiler room shot?
