Thanks for the replies so far.
Bart B. - The rifle is a .308 Win. I plan on using Sierra 175 gr MatchKing bullets. My barrel is 26" with a 1/10 twist rate.
I am guessing load development is going to be somewhat of a long process in comparing many different loads to see how they shoot in my rifle. My Lyman and Sierra loading data books are just a starting place for the recipe that works best in my rifle.
