Home Forums Hunting & Shooting Ask The Gunwriters Why the 11-1/2 twist in the Stevens 7mm-08 ?

It's an interesting response given that their manual states the projectile used to test their 7/08s is the 140gr Ballistic Tip.

I'd have bought a Stevens 200 in 7mm/08 if they'd have kept the older 1:9" twist ... I dont see Savage making 308Win rifles in 1:13" (perfect with 155gr) so cannot understand the reasoning behind the 1:11.5" twist.

Savage has some damn smart cookies in their R & D dept.

Marketing also makes decisions to please 80%-90% of the shooters that buy their products.

The 1-11.5 is going to produce some really exceptional accuracy, wait and see. They don't just pull this stuff out of their butt, it is the result of a bunch of testing and many meetings discussing the pro's and con's. To make a move like this, there had to be exceptional accuracy...bottom line.

I built a 7 Mag with a 1-12 and according to the Green Hill formula, the 140g Ballsitic was not supposed to stabalize, but it shot groups too small to talk about, it also shot the 150g Ballsitic tips extremely well also. I had a hoarde of the 140's, that is what I stuck with. I got 3350 out of the 140's, no pressure issues with IMR 4350.

Ruger,

Have you shot it yet ?

Maybe try these 120 grain ? Little tougher than standard C&C, but not premiums either.

From what JB was saying, may suit the slower twist.

Howver, the 200 is shown as 1:11.5

Figure that out.........

I used to have a 7/08 in a Remington 788 and loved it. It was very accurate and light recoiling with everything except some 154 grainers that I loaded up which made the recoil feel like an '06. Actually my favorite loads were made up with 130 grain speer bullets. I guess if the 11.5 ROT is best for 140 grain bullets and below - why not! That just makes the 7X57 more flexible with it's heavy bullet capability.

Now that sounds foul, two different twist for two models in the same chambering by the same mfg. who IIRC makes their own bbls?

Hmmmmmm, is that true, or could there be a typo?

I has got to be a typo. Its the only 7mm-08 on the entire sight with a 1-9 twist. Even the other 16 series rifles have teh 1-11.5

Well now Savage says .We have not change it as yet ,but the 11.5 is for a lighter bullet. the web sight is wrong there not made as yet, Just got off the phone with them

Ruger,

Have you put her over the bags yet ?

I bet it will shoot the 120's, but ? the 140's.

As I said on the other thread, I'm looking at a Savage combo for my 14 year old son, so he doesn't have to share Mommas .243 any more.

Paul.

Need some clarification here.

The web site shouldn't list them as 1:11.5, or as 1:9 ?

Which one isn't made yet ?

Paul.

Con, did you find this on-line, if so, can you post a link please ?

Paul.

I'm a little whipped in that I allowed my wife to pay for the rifle but then she put it away till Christmas. Maybe I can get my Man Card back by then.

Hmm, looked at the sight, no email service for CS, no toll free, but the specs surely are 11.5 for the 7/08, and oddly, an 11" for the 270 WSM, NEVER seen anything other than a 10" for a 270 cal.

Savage is not sticking to traditional twist in all cal. Oddly the 223 is a 9", vs. many 12 and 14 bolt rifles, though the 22-250 is a 12". They must understand many 223s might be shot with heavies, but they do not apply that logic consistently across the cartridge line up.

Their 7 mags have 9.5 listed, SO if there is ANYWAY possible they incorrectly trasposed numbers, I can see using the same equipment to make mag bbls as 7/08. Makes sense, but does not guarantee.

My GUT tells me somethings GOOFED, hopefully a typo. ALL other rounds have twists in line with industry norm/averages.

22-250 REM 1 in 12"
243 WIN 1 in 9.25"
7MM-08 REM 1 in 11.5"
308 WIN 1 in 10"
223 REM 1 in 9"
204 RUGER 1 in 12"
250 SAV 1 in 10"
300 SAV 1 in 10"
270 WSM 1 in 11"
300 WSM 1 in 10"

No problems, dude. BTDT !

Paul.

& I hope your season is longer than ours, 'cause by Christmas, we're done !!

Paul.

We have till January 31st for deer and all year on hogs. I told her that I will have everything ready to go on the rifle the day after Christmas so I have a good chance of getting it bloody this season still.

Keep in mind that the button rifling may, or may NOT, give the exact rate that's listed, too.

Over on .204ruger.com some of the guys measured their Savages' twist rates, and most of them went 1-12.25" to 1-12.5", due to the tolerances in rifling machinery. Since the 40 VMax is such a long bullet, (it's "barely stable" in a true 1-12" barrel), there's no wonder why everyone likes the shorter Sierra 39gr. bullets.

It's just as likely the 7mm/08 Savages will suffer from the same malady.

Cheers & good luck !

Can't remember, but I think I recall you use factory ammo, like me ?

I found that Federal Fusions come in a 120 grain, maybe that would be the way to go ?

I can't get them from my local (400 kilometres away) Cabelas, though, they are only carrying the 140's !

Paul.

Well, boys and girls, I had a Stevens 200 in 7mm-08 three years ago that shot 160 gr Accubonds just fine, so there was definitely a much faster twist than 1:11.5 in that barrel.

IIRC, I posted about that on CGN. We were having a discussion about the 1:12 twist barrels on the Husqvarna Lightweight 7X57s, and I mentioned that they would not stabilize the ABs, but the Stevens 7mm-08 would.

If they are actually 11.5 twist now, then they have been changed.
