Thanks for the posting. This certainly updates my 2003 listing!

Let's make a "Sticky" of this as the question comes up quite frequently. A Sticky will save a lot of used bandwidth by others answering the same question.

Not sure if you are wanting updates or not Rangr, but here are a few just from guns I own.

1. The early run Savage Axis/Edge 7-08s had a 1-11.5" twist. This was not popular and it would not surprise me if they have adjusted in later years.

2. My Ruger Model 77 MkII .350 Rem Mag has a verified 1-12" twist.

You may wish to add the Remington 788, 6mm Remington, 1:9 twist.

Also, the CZ550 American, 9,3x62 is 1:10 twist. Most double rifles chambered 9,3x74R have
a 1:14 twist. I've only run into one bolt gun in 9,3x62 with a 1:14 twist, most seem to be
1:12 or 1:10, current production. I'm sure the older rifles might be 1:14.

Update this for the M1A, you'll find them with barrels from 1 in 10 to 1 in 12. I normally use 1 in 11 Kreiger Medium grade.

Does a fast twist rate (1:8"), coupled with a long-for-caliber bullet at moderate velocities equal better penetration? Or was Walter "Karamojo" Bell wrong in that assessment? If a long, heavy bullet trucking along at 2,400 fps spins around 3,500 r.p.m., will it penetrate deeper than the same bullet coming out of a barrel with a slower twist rate? Say 1:10"?

(Lets pretend he never killed dozens of elephants, cape buffs and other African game with just his 7x57 Mauser...).

Discuss...

I just noticed that you list the Cooper in 222 Remington and 223 Remington as 1 in 14" twist. According to their current catalog the twist rate for both is 1 in 12". However, it could be that previous year's Cooper rifles were 1 in 14".

Thanks.

I put the list together from several different sources, all of which were missing info from the other sources - plus, I added some I have personal knowledge of.

Just For "Giggles":
.25ACP/6.35 Browning Barrel Blanks 23.4" long have a Twist listed as 1:9.4" (Update 2016 Barrels are 1:9.8" rate).
This is Both a Rifle AND a Pistol caliber Now.
.25 Stevens (Long) Rf shares Barrel Dimensions with the .25ACP/6.35 Browning.
6.35x32mmSR is specified as 1:9 Twist but practical use is in a LW 1:9.4 Twist barrel.
6.35x28.6mmSR is specified with 1:9.4 Twist.
(ADDED 2016) 6.35x26mmSr is specified with 1:9.8" twist
Both of these use '.250-.251 inch diameter Bullets' .

I am having a Ruger 'Single six' converted to .25ACP/6.35x28.6mmSR with a 10-5/8 inch LW Barrel and two reamed out Replacement .22WMR 8-Shot Cylinders purchased from "Numerich Arms" and work being done by "American Gun Works" in Glendale, CA.

My Rifles are CF converted Stevens Favorite Based and I am using a Stevens ".25 Stevens" barrel for the 6.35x28.6mmSR in a Rifle.

Best Regards,
Chev. William

Twist changes in relation to what?

Do you go for a faster or slower rate of twist with heavier bullets? Do you want a faster or slower rate of twist with cast lead bullets?
I am working with a 45-70 bolt gun my Uncle built up. He got into cast bullets but I don't know if he built the gun for cast bullets.

I would argue that for any 6,5 cartridge, 1:8 rate of twist;
further, 7mm cartriddge, 1:9 rate of twist; 45-70 cartridge,
1:20 minimum rate of twist, or faster; not micro-groove;
358 cartridge, 1:12 rate of twist (sorry Remington,
you -------up again with your 1:16. And for all of you 358 fans
who wonder why it never took off, you might wish to blame
Remington with their 1:16 that wouldn't stabilize a 250 grain bullet.
Assuming in all of the above choices the hunter is using jacketed
bullets, with the exception of the 45-70.

I would argue that you can't define the rate of twist you want for any bullet diameter until you've defined the bullet style/weight you are going to shoot. It would make no sense to build a 22-250 rifle with a 1:7 twist, if you planned on using nothing but 50 grain bullets. If you wanted a 6.5 Varmint Destroyer, a 1:8 twist would slow ya down.

Thanks to the OP for posting so much credible information in one place. :)
