    30-06 or 270 whats the flatest round?

    hi folks

    i'm after a new stalking rifle and have the above 2 calibers in mind. which has the flatest round and is there any benifits in one caliber over the other?

    i am going to use the rifle mainly for open hill stalking.

    many thanks

    The difference at under 150m in trajectory is so small as to be negligable. But I will let the balilstic experts give you all the stats. 30-06 has a certain something, but do test fire both, in various different rifles - both have a bit of a kick to them in light rifles.

    Ally, the flattest round, will depend on a number of factors, including bullet weight, type, what range you are zeroed at, and how far you want it to be flat to etc

    Example a 30-06 is going to be flatter shooting a 125gn bullet than a 270 shooting a 150gn bullet.

    The most common loads are the 270 using a 130gn bullet vs the 30-06 using a 165g or 180gn bullet (although 150/155 are also common).

    The lighter bullets for calibre are flatter initially, but they loose their momentum quicker than a heavier bullet, also the lighter bullets tend to be more affected by wind.

    You also need to consider the way they behave on impact if a short range shot presents itself, a lighter faster bullet can expand too quickly as the impact velocity is still very quick.

    In real terms they are both great calibres, and its a case of you reaching a balance that will suit your individual stalking best. The balistic differences between the 2 are almost negligable in real terms until you reach 3-400yds+

    Hope that helps

    the difference between these two and many other popular stalking chamberings is so small to not matter one jot out to 200yds.

    Very true !
    Correct placement of the shot with a well designed hunting bullet at a sensible distance is the answer.

    After come years of (recreational) hill-stalking, I came to the conclusion that it was probably not without reason that .270 was for many years the standard hill-stalking cartridge. I now have a .270.

    As remarked, however, 'flatness' depends in absolute terms on bullet ballistic coefficient and weight and its muzzle velocity; and in relative terms on the way you set your sight.

    I got a .270 stainless/synthetic to replace a similar 6.5x55 for the hill. I could have gone for .30-06 or 7x64 or something, but I already have a (wood and blue) .308, and cases/cartridges for .270 are much commoner than 7x64.

    My summary would be that between .30-06 and .270 there probably isn't a whole heap in it, given the wide range of bullets/loads you can get for both.

    unless you plan on chucking larger round above 150gr the 270 does all you need

    the 06 comes into its own when looking for heavier loads

    flat shooting rounds are a myth unless you are firing sub 50gr at 4000+fps

    pretty much ALL popular stalking calibres shoot within an inch or so of each other at 100 200 and even out to 300

    Depends on what you want to shoot if one day you decide on going to shoot some pigs or plains game i'd go for the 30-06 cos you can go over 200 grns with your bullet wieght if you need to

    I went the 30:06 route, simply as it gives a wider range of bullet weights, so i can go for boar one day. I am finding the trajectory of my 30:06 and 243 are incredibly similar in the ranges i shoot out to. The 243 is running 100gn and the 30:06 165gn and both are point and press. I am no expert, but really happy. I now have two matching rifles so safety's and everything else feels totally natural with both rifles. Different scopes make the easy to tell apart however.
