The current 1/10 will stabilize everything commercially available for the .270 Winchester. If you wanted to go any faster you would also need to decide on a bullet swagging set up.

There is a difference between stabilize and optimum stabilization. The subject clearly states "If you were interested in a fast twist 270"... If you're not interested find another thread to participate in. Thanks, David

And considering all the .270's I own, and have shot, I know a little bit about the subject. The only reason to go faster in a .270 is if you are swagging your own bullets.

If you're about to start a new thread, it would be tough to beat this informative start.
It's official. I missed the selfie deadline so I'm Maser's sock puppet because rene and the Polish half of the fubar twins have decided that I am.

I would use a 1 in 9 twist. I actually have a blank sitting here but my Rem 700 CDL 270 Win shoots quite good, was going to do a 270 Wby to go with it but decided the 270 Win is plenty good for me.

Why 9" and not 8"? Is it because you think 8" will cause problems with conventional 130grn loads or you just don't have anything you want to shoot that will benefit from an 8" over a 9"? Another reason? Thanks! David

David I've had some 9 twist 270's. Used to be all I ordered. But it's been awhile since I've had to order a 270 barrel....maybe 3-4 years. I just sold a rifle with a 9 twist Brux....didn't like the contour but the twist was fine.
The 280 Remington is overbore.
The 7 Rem Mag is over bore.

I have zero experience with a 270 other than a 10" twist, so trying to learn here. Looking at Berger's online twist calculator it looks like an 8" would be a (slightly) better choice for some bullets like the Barnes LRX and Berger 150's. Doesn't look like it should be a problem with conventional 130's. David

Another reason? Thanks! David I just ordered something a bit faster than standard which is why I went with a 1 in 9. I would think a 1 in 8 would be fine but maybe someone else would be able to answer that better. I believe Matrix makes some bullets that require a faster twist than a 1 in 9. All I know is that bullets are getting longer all the time so having something faster doesn't hurt.

The current 1/10 will stabilize everything commercially available for the .270 Winchester. If you wanted to go any faster you would also need to decide on a bullet swagging set up. I agree. 10 twist has done everything I've ever needed with the 130 to 150 grain pills. If I were to twist faster, I guess it would be for 160 Nosler partitions and a 9 twist may be optimal. But IME there is no need, since 130 through 150s do everything needed in NA with a 270.

David back in the 80's I just took Bill Steigers advice and got a 9 twist. Could have gotten an 8 twist but he said 9 was fine....at the time. I can't recall ever having been disappointed. IIRC most were Kriegers.
Bullets are longer today and,as you pointed out, an 8 twist could be needed to stabilize some of them.
I wouldn't be afraid to get an 8 twist today. Go for it!

If you want a fast twist 270, might as well go with an 8.
All of mine have been 10's with no complaints. Have not had any issues with 85-160gr bullets.
I do have some 180gr Woodleigh's that have not been spectacular, but I have not gotten too serious about them yet. They may benefit from a 9 or 8 twist.

Ironically my 1 in 10 twist Rem 700 CDL does great with the 160 gr Partition, so far the best accuracy of any bullet. Going to probably save the extra 1 in 9 Benchmark barrel for when this one gets shot out in a few years time. The ultra long 180 gr Woodleigh may need more twist but it appears the 160's do fine. ![[Linked Image]](http://i276.photobucket.com/albums/kk31/gerrygoat/P1020199_zps5eu5n1zq.jpg)

David I would go with 9". Might not be needed with most of today's .277 bullets but it sure won't hurt anything and with increased demand for the long range stuff, longer .277 bullets may be available in the future. John

Have an 8 twist #2 Lilja inbound. Will be chambered .270 Win. Also have 160, 170 and 180 grain .277" bullets on hand. Will report back in a few months after I get it put together and do load development.

My Steyr Prohunter 270 has 8.6 twist. Mine works great with some factory ammo in 130 and 150 grain, and throws some factory loadings in a pattern instead of a group.
