Re: help with entry to long range shooting
Ok...to start off with, you 'aren't exactly sure what an action is'. That in itself should be your first clue as to what course of action to take first. Before spending your hard earned money on a platform, I recommend spend a little less money and learn. Get a hold of some books regarding sniping, ballistics, basics of target shooting, operations and components of rifles. Talk with a couple of gunsmiths, competition shooters, etc. The more info you can acquire, the better armed you'll be in choosing the correct system.
Groper gave you some killer advice. 300 yards is not long range, not even close. Long range begins somewhere (and many people have differing opinions) in the vicinity of excess of 600 yards. You also have ELR shooting (extreme long range) which consists of 1200 yards and beyond.
Let's say you get your .308 and your happy with eventually working up a load and your zero to 1,000 yards. Cool, now what happens if you try to use that same load and zero to really drop something? Nothing. Putting holes in paper isn't the same as having enough energy to really use on game. Reallistically, a .308 is only effective for terminal ballistic performance to about 800 yards, but is well capable of putting 'holes in paper' past 1000. What happens if you want to reach further than 1000?
When it comes to long range shooting, it is no longer a simple issue of lay the crosshairs on target, breath easy, relax and sqeeze off the shot. A whole lot more comes into play. So many aspects apply to affect your bullets trajectory, that when you miss, you're confusion as to which aspect caused your miss will drive you crazy.
So, do the research now, before you go buying anything. The three most fundamental aspects of accurate shooting are 1)the shooter, 2)the ammunition and 3) the rifle. However, each one has a multitude of aspects to be learned, understood and mastered.
