I've shot the 270 Win for about 17 years now and reloaded 10's of thousands of rounds. The advice to start low and work up is SOUND. Why go to MAX and pay that price over years of service, when a suitable, just as dead, hunting combination can be loaded with less powder and the "savings" that offers over time? Italicized because you are gonna shoot just as much one way or the other. Why not spend fewer dollars for all that fun?
I can visually see when the load and rifle/bullet combination are well suited for one another by the way the groups tighten up on paper at the range. I can't tell the difference at the shot and the game can't tell the difference at impact whether the bullet is traveling 25 or 50 feet per second SLOWER than a faster (i.e. more powder) bullet. Dead is dead - right?
What I want is the confidence to KNOW that when I point the gun at something and pull the trigger, that bullet is going to go EXACTLY where I pointed it. If I can get that confidence with less powder - WOO HOO!
Work up a load that gives YOU confidence and forget all the rest. MEAT is what you really want. You can't eat horns...
