My current load for my .308 rifle is as accurate as my skills will allow, and has a one shot DRT on a 250 pound ferrel pig to its credit. Even though I hunt with it, when I put this rig together its primary function was target shooting. My wife has informed me that as soon as we get over a couple financial hurdles, she is going to send me on one of those primo guided big game hunting trips. She even advised me to start looking at at putting together a new rifle. This rilfle's sole purpose will be hunting. My caliber of choice is nothing fancy, just a good ole fashioned .30-06 with the same barrel profile as my .308. Here is my question. If I'm going to use the same 175 grain bullet that I use in my .308, should I use the same powder or a slower one.
