Re: 178gr AMAX vs 175gr SMKs?
I shot the SMKs for a long time with great results from a .308 and .300wm. When the AMAX came out, I wasn't a huge fan of Hornady (for no particular reason) I just always had great luck with Sierra and stuck with them for my reloading. However, a buddy of mine gave me 100 AMAX to try and I found that they work every bit as well as do the SMKs. All in all, unless one shoots better out of your gun (which is possible) I'd go with the Hornady as they are less expensive and produce near identical results.
