Home Forums Hunting & Shooting Hunting Rifles .308 Win 1:12 Twist

Is this something to stay away from? I have my eye on a Win M70 Extreme Weather, in .308 but Winchester's website says it's a 1:12 twist. I' most likely be shooting 165gr bullets out of it. Is that enough to stabilize them? I thought generally .308/30-06 had a 10 twist.

The 1/12 twist should be fine up to a 180 grain flat base bullet at sea level, it will be marginal with a 180 boat tail though. I prefer the versatility of a 1/10 twist.

I tried 208 amax in my 1/12 308 at 4500' and it wasn't as accurate as it was with the 168 amax I suspect they were on the verge of being unstable. Montana Marine has had good luck with the 208 in his 1/12 and that is why I tried them.

No worries, mate. 1:12 will suffice nicely with the 165's.

My 1:12 m70 featherweight shoots the 168gmm really well. I wouldn’t sweat it.

You should have no worries at all.

Thanks guys.

So you have a question, about a twist rate, and will it stabilize certain bullet weights....

The manufacturer Winchester has customer service dept,

Bullet manufacturers have customer service depts...

Yet you choose to ask people on a web site, instead of going to the source...

AND YOU GIVE ME SCHITT, AND CALL ME THE DUMBASS?

ya wanna see the moron? look in the mirror while you brush your teeth...

there ya go!

Party on Garth.....

if i recall correctly the 1-12 was meant to be ideal for the 168 SMK and the 1-11.25 came along for the 175 SMK. makes for a fun story, at least

Well, tzone DID ask BEFORE going hunting/shooting with them.

I have shot 200 NABs out of my 20” 1:12 .308 before just to see. Sea level and 20 degrees. Didn’t key hole at all and actually grouped decent. 180 accubond sand 180 sciroccos,178 eldx all shoot great. You’ll be more than golden with 165s.

Excellent. Thank you.

So did I Mr Skane... 30 days before I went hunting with the bullet and the load.. I asked the manufacturer for any load data recommendation, and asked about the bullet performance parameters... but being a brand new product the customer service rep evidently have any supplied information... he was just shooting from the hip and referred to it being like a ballistic tip, and that it would open up at low impact speed....

which turned out to be wrong....hence the call to the manufacturer, when I got to within cell service
AFTER CALLING 4 DIFFERENT BUDDIES TO ARRANGE ASSISTANCE on recovering the deer at an early and safe opportunity....

I also tested the bullet for accuracy at ranges out to 300 yds, at my local range before deer season even opened.. but I guess no one does that, so they assumed I don't either...

I submit that to you with respect...

Tzone? Tommy boy can kiss my A*^.....

180 Accubonds would have my interest as do the 165's. What ranges are you shooting? What are you using for glass?

In a 308? What are you hunting?

A 1-12” twist in a 308 will stabilize flat base 200 grain jacketed bullets, at normal hunting velocities. I tried it in a Rem 700 Varmint Synthetic 308 Win. With 1-12” factory barrel and Speer 200 grain .308 bullets ( near max load of IMR 4350), with groups well under 1.5 moa.

Here’s a link from accuratereloading.com “medium bore” sub-forum. 308 Win shooters are reporting great accuracy with 220 grain jacketed bullets in 1-12” twist barrels ( with surprising velocity, 2350-2400 FPS).

Great rifle, and chambering. Get it and use it with confidence.

Deer. 99% of the time.

I had a Browning Abolt with 1:12 twist that did fine with 150-165. I really didn't need to try anything heavier. Currently I have a Bergara with 1:10 and it did not like the lighter bullets but likes likes 165-178s.

Thanks for the link.

I had an older one in .30-06 but it was a bit of a tank. I do like the newer, slimmer version enough be seriously considering it.

TZ,

308 is my primary rifle for deer and feral pigs.

Couple of suggestions fwiw.

The 130 Barnes TTSX is pleasant to shoot and performs wonderfully.

The 150 Partition wells well too if a lead bullet is preferred.

Varget and a F210 works well with both, as well the whole range from 135 - 185’s.

As others have posted 1:12” will work nicely, up to 185 Bergers in my experience.

Great deer hunting choice, enjoy.

My dad hunted two loads in a 20" SPS-T 700 with a 1-12" twist. One was the 130 TTSX at 2,950fps with TAC, the other was the 200gr Sierra BT Gameking at 2,600fps over RL17. Two very different loads, but both were very effective on deer.
