You might have some problems with the Amax at those speeds. From what I understand, 3450 is about as fast as you can run them without blowing them up. The jacket is pretty thin so they can't withstand the high velocity. It you want to run the amax in particular, there's no point in improving the std RUM case because you can get that velocity easily. Where the improved cases really shine is when you're using the heavy for caliber bullets. If you look at some 180g bullets you might gain something but those custom bullets are a lot of money per shot. I know Kirby is working on some custom bullets of his own so that may work for you also. The 168g SMK's will blow a giant hole in a deer and the jacket is a little thicker. The only downfall is the bc isn't as good as it should be for the bullet weight. You might want to try the sst or interbonds from Hornady. The bc's are good and the jackets are thicker than the amax. Either way you go, 3450 with a 162g amax is like shooting a 220swift with 45g bullets to 500yds. Keep the amax off of the front end if you want to eat it
