Re: need help starting out
What kind of help do you need??
The 308 make a very potent weapon at 500 yards, even 1000 with the right gun and loads. 308s are hard to beat, they make tons of bullets weights and styles and are VERY accurate even at 500+ yards. In the hands of a skilled reloader one can drive heavier bullets with higher coefficients faster with the 308 than with the standard 243 or even the 7mm08. A 7mm08 would be a little easier on the shoulder but not enough to notice. Remington 700 pss or vssf or even the vs make very accurate out of the box rifles and custom rifles can be made to fill any desire you have.
Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
