I am currently looking at a new centerfire bolt action rifle, and I must say, things are different now than they were 10 years ago. So much selection, and accuracy for affordable prices. I even worked the bolts at a local store of the Mossberg and TC, etc. so smooth for cheap guns.
I got soured on the larger (.30 cal. and above) bolt actions years ago as they always had some kind of problem, accuracy was inconsistent, it seemed that you had to drop time and money into them to get the gun to shoot tight groups. Nice to know there might be future for one of the new bolt actions in my gun safe, looking at .270 or .308 as the ammo is available.
Chris,
With factory ammo out to 200 yards you are not going to have a problem with either caliber off the bench.
Personally I like 308 over 270Win. Both work. and even if you get a 3" group at 200 yards that is still good enough to stick a bullet in the boiler room on a deer sized animal. I think you are going to have more trouble with winds wipping around the woods, ridgelines, or fields more than the accuracy of the rifle.
I think some of the accuracy claims made by some people are what is causing concerns with their rifles.
I just got back from Montana where I was helping a buddy elk hunt. His cousin made some holly cow statements to me about his 7mm Mag.
statement 1: his reloads had him tossing a 165 grain bullet at just under 4,000 FPS with only slight signs of pressure.
statement 2: his reloads had him shooting "Inch and a half groups at 300 yards, off the bench of course".
I looked at him and said "that's great" In my head I was yelling NO POSSIBLE WAY! I wanted to reach into my wallet and bet him $20 a shot he could not do that.
7mm mag loads in every book I have ever looked in have a 160grain bullets at max about 3K to 3,200 I can understand maybe getting the bullets 5 to 10% over max with new loading data and powders. But not 30%
the accuracy was not to be believed either. While you may get 1/2" at 100 yards, you may get 1" at 200 yards (in an indoor range with no ventilation)
You will not get 1.5" groups at 300 yards for any number of reasons. The first being wind. The second being the bullet will have micro dents, as well as actual dents in the jacket or the exposed lead, or polymer that will move the bullets farther than that apart. The powder has to be exact, loaded on the same day for humidity, and the primers have to be exact, the wind and the barrel, ground, ammunition, temperture, and fouling would have to the same.
Things that are not possible to produce that small of a group over 300 yards.
After all your chrono gives you a standard divation. You may weight out every charge two or three times to make sure they are prefect but you will still get a divation in your speeds. Those divations are what spread your groups.
