Tikka t3 270 Win. 1:10" twist most accurate bullet weights
- Thread starter p5200
- Start date
The Sierra 90 grain HP is also pretty accurate and there are some newer bullets that I haven't tried that are supposed to be good.
Accuracy is more than grouping ability; however. Accuracy in a hunting rifle also involves flatter trajectory and minimized wind deflection. That's why I shoot 130 grain, plastic-tipped, boat tail bullets at 3,200+ fps. in mine. I can sight in to zero at 230 yards and be within 3" of line of sight out from zero to over 300 yards.
This is critical to my deer hunting, since I have a stand that allows me to shoot deer from 20 to 450 yards and I've shot them at all the ranges in between, but the shooting window is very narrow, slightly more than a deer's length and they usually cross within 10 seconds, so there's no time to adjust sights or compute holdover in most cases. We rest rifles on a padded board in the ground blind with the rifle in shooting position. I like to be looking through the scope most of the time and aim for the shoulder or slightly ahead, depending on range and deer movement. My accurized Rem 700, .270 Win, grouping under 3/4" at 100 yards, is just the ticket!!!

I think you will have to see what your rifle likes best but for my Winchester M70 with a 1:10 twist, I got best results on average with 130 grain bullets but the results were mixed.
Core LOKT Remingtons 130s shot best with IMR 4350 powder and Sierra Game King 130s also shot good with IMR 4350.
Nosler Ballistic Tip 130s shot good with R-22 powder.
But the 140 Nosler BTs shot 2nd best overall with IMR 4350 powder.
I didn't try many 150 grain bullets because they shot pretty bad.
Interestingly, 130 Nosler Partitions didn't shoot all that well.
Neither did the 140 Nosler Accubonds (they were about the worst overall).
It appears that bullet weight might not be as important to accuracy as bullet shape (the amount of bullet touching the rifling) when the bullet weight difference is only 10 grains.

150 grain Nosler Partition
My model 70 Winchester has a 1:10 twist. The best load by far at 300 yards utilizes a 150 grain Nosler Partition at right around 3,000 fps.

It's been mentioned before, but it seems that the .270 Win has a tendency to shoot different weight bullets to the same POI at a given range. Mine shoots both 130 grain and 90 grain bullets within a half-inch of each other at 100 yards.
In my experience, that trait is rare, but really great!

The 270 as popular as it is, is one of the most underrated cartridges out there.
With the modern high BC bullets we have today the 270 is an excellent long range round.
The 130 gr is quite effective but for long range hunting I like the 150's. Ib holds up better, retaining velocity and energy.
Berger makes an excellent 150 but my Model 70 likes Hornady.
For hunting I like hornady's 150 IB. It's a tad expensive but worth it. For practice and target shooting I use the cheaper Hornady 150 SST. It has the same BC as the Interbond meaning I can use the same load, the same zero and sight settings across the board.
